LM20143MH资料

January 16, 2008 LM201433A, PowerWise® Adjustable Frequency Synchronous Buck RegulatorGeneral DescriptionThe LM20143 is a full featured adjustable frequency syn-chronous buck regulator capable of delivering up to 3A of continuous output current. The current mode control loop can be compensated to be stable with virtually any type of output capacitor. For most cases, compensating the device only re-quires two external components, providing maximum flexibil-ity and ease of use. The device is optimized to work over the input voltage range of 2.95V to 5.5V making it suited for a wide variety of low voltage systems.The device features internal over voltage protection (OVP) and over current protection (OCP) circuits for increased sys-tem reliability. A precision enable pin and integrated UVLO allows the turn-on of the device to be tightly controlled and sequenced. Start-up inrush currents are limited by both an internally fixed and externally adjustable Soft-Start circuit. Fault detection and supply sequencing is possible with the integrated power good circuit.The frequency of this device can be adjusted from 500 kHz to 1.5 MHz by connecting an external resistor from the RT pin to ground.The LM20143 is designed to work well in multi-rail power supply architectures. The output voltage of the device can be configured to track a higher voltage rail using the SS/TRK pin. If the output of the LM20143 is pre-biased at startup it will not sink current to pull the output low until the internal soft-start ramp exceeds the voltage at the feedback pin.The LM20143 is offered in a 16-pin eTSSOP package with an exposed pad that can be soldered to the PCB, eliminating the need for bulky heatsinks.Features■Input voltage range 2.95V to 5.5V■Accurate current limit minimizes inductor size■97% peak efficiency■Adjustable output voltage down to 0.8V■Adjustable switching frequency (500 kHz to 1.5 MHz)■32 mΩ integrated FET switches■Starts into prebiased loads■Output voltage tracking■Peak current mode control■Adjustable Soft-Start with external capacitor■Precision enable pin with hysteresis■Integrated OVP, UVLO, power good and thermal shutdown■eTSSOP-16 exposed pad package Applications■Simple to design, high efficiency point of load regulation from a 5V or 3.3V bus■High Performance DSPs, FPGAs, ASICs and microprocessors■Broadband, Networking and Optical Communications InfrastructureTypical Application Circuit30030501 PowerWise® is a registered trademark of National Semiconductor Corporation.© 2008 National Semiconductor LM20143 3A, PowerWise ® Adjustable Frequency Synchronous Buck RegulatorConnection Diagram30030502Top VieweTSSOP-16 PackageOrdering InformationOrder Number Package Type NSC Package DrawingPackage MarkingSupplied As LM20143MH eTSSOP-16MXA16A20143MH92 Units of Rail LM20143MHE 250 Units of Tape and Reel LM20143MHX2500 Units of Tape and ReelPin DescriptionsPin #Name Description1SS/TRKSoft-Start or Tracking control input. An internal 5 µA current source charges an external capacitor to set the Soft-Start ramp rate. If driven by a external source less than 800 mV, this pin overrides the internal reference that sets the output voltage.

This easy to use regulator features two integrated switches and is capable of supplying up to 3A of continuous output current.The regulator utilizes peak current mode control with nonlin-ear slope compensation to optimize stability and transient response over the entire output voltage range. Peak current mode control also provides inherent line feed-forward, cycle-by-cycle current limiting and easy loop compensation. The switching frequency can be varied from 500 kHz to 1.5 MHz with an external resistor to ground. The device can operate at high switching frequency allowing use of a small inductor while still achieving efficiencies as high as 96%. The precision internal voltage reference allows the output to be set as low as 0.8V. Fault protection features include: current limiting,thermal shutdown, over voltage protection, and shutdown ca-pability. The device is available in the eTSSOP-16 package featuring an exposed pad to aid thermal dissipation. The LM20143 can be used in numerous applications to efficiently step-down from a 5V or 3.3V bus. The typical application cir-cuit for the LM20143 is shown in Figure 2 in the design guide.PRECISION ENABLEThe enable (EN) pin allows the output of the device to be en-abled or disabled with an external control signal. This pin is a precision analog input that enables the device when the volt-age exceeds 1.2V (typical). The EN pin has 100 mV of hys-teresis and will disable the output when the enable voltage falls below 1.1V (typical). If the EN pin is not used, it should be connected to VIN. Since the enable pin has a precise turn-on threshold it can be used along with an external resistor divider network from V IN to configure the device to turn-on at a precise input voltage. The precision enable circuitry will re-main active even when the device is disabled.PEAK CURRENT MODE CONTROLI n most cases, the peak current mode control architecture used in the LM20143 only requires two external components to achieve a stable design. The compensation can be select-ed to accommodate any capacitor type or value. The external compensation also allows the user to set the crossover fre-quency and optimize the transient performance of the device.For duty cycles above 50% all current mode control buck converters require the addition of an artificial ramp to avoid sub-harmonic oscillation. This artificial linear ramp is com-monly referred to as slope compensation. What makes the LM20143 unique is the amount of slope compensation will change depending on the output voltage. When operating at high output voltages the device will have more slope com-pensation than when operating at lower output voltages. This is accomplished in the LM20143 by using a non-linear parabolic ramp for the slope compensation. The parabolic slope compensation of the LM20143 is much better than the traditional linear slope compensation because it optimizes the stability of the device over the entire output voltage range.CURRENT LIMITThe precise current limit of the LM20143 is set at the factory to be within 10% over the entire operating temperature range.This enables the device to operate with smaller inductors that have lower saturation currents. When the peak inductor cur-rent reaches the current limit threshold, an over current event is triggered and the internal high-side FET turns off and thelow-side FET turns on allowing the inductor current to ramp down until the next switching cycle. For each sequential over-current event, the reference voltage is decremented and PWM pulses are skipped resulting in a current limit that does not aggressively fold back for brief over-current events, while at the same time providing frequency and voltage foldback protection during hard short circuit conditions.SOFT-START AND VOLTAGE TRACKINGThe SS/TRK pin is a dual function pin that can be used to set the start up time or track an external voltage source. The start up or Soft-Start time can be adjusted by connecting a capac-itor from the SS/TRK pin to ground. The Soft-Start feature allows the regulator output to gradually reach the steady state operating point, thus reducing stresses on the input supply and controlling start up current. If no Soft-Start capacitor is used the device defaults to the internal Soft-Start circuitry re-sulting in a start up time of approximately 1 ms. For applica-tions that require a monotonic start up or utilize the PGOOD pin, an external Soft-Start capacitor is recommended. The SS/TRK pin can also be set to track an external voltage source. The tracking behavior can be adjusted by two external resistors connected to the SS/TRK pin as shown in Figure 7.in the design guide.PRE-BIAS START UP CAPABILITYThe LM20143 is in a pre-biased state when the device starts up with an output voltage greater than zero. This often occurs in many multi-rail applications such as when powering an FP-GA, ASIC, or DSP. In these applications the output can be pre-biased through parasitic conduction paths from one sup-ply rail to another. Even though the LM20143 is a syn-chronous converter it will not pull the output low when a pre-bias condition exists. During start up the LM20143 will not sink current until the Soft-Start voltage exceeds the voltage on the FB pin. Since the device can not sink current it protects the load from damage that might otherwise occur if current is conducted through the parasitic paths of the load.POWER GOOD AND OVER VOLTAGE FAULT HANDLING The LM20143 has built in under and over voltage compara-tors that control the power switches. Whenever there is an excursion in output voltage above the set OVP threshold, the part will terminate the present on-pulse, turn-on the low-side FET, and pull the PGOOD pin low. The low-side FET will re-main on until either the FB voltage falls back into regulation or the zero cross detection is triggered which in turn tri-states the FETs. If the output reaches the UVP threshold the part will continue switching and the PGOOD pin will be asserted and go low. Typical values for the PGOOD resistor are on the or-der of 100 k Ω or less. To avoid false tripping during transient glitches the PGOOD pin has 16 µs of built in deglitch time to both rising and falling edges.UVLOThe LM20143 has a built-in under-voltage lockout protection circuit that keeps the device from switching until the input voltage reaches 2.7V (typical). The UVLO threshold has 45mV of hysteresis that keeps the device from responding to power-on glitches during start up. If desired the turn-on point of the supply can be changed by using the precision enable pin and a resistor divider network connected to V IN as shown in Figure 6. in the design guide.THERMAL PROTECTIONInternal thermal shutdown circuitry is provided to protect the integrated circuit in the event that the maximum junction tem-10L M 20143perature is exceeded. When activated, typically at 160°C, the LM20143 tri-states the power FETs and resets soft start. After the junction cools to approximately 150°C, the part starts up using the normal start up routine. This feature is provided to prevent catastrophic failures from accidental device over-heating.LIGHT LOAD OPERATIONThe LM20143 offers increased efficiency when operating at light loads. Whenever the load current is reduced to a point where the peak to peak inductor ripple current is greater than two times the load current, the part will enter the diode emu-lation mode preventing significant negative inductor current.The point at which this occurs is the critical conduction bound-ary and can be calculated by the following equation:Several diagrams are shown in Figure 1 illustrating continu-ous conduction mode (CCM), discontinuous conduction mode, and the boundary condition.It can be seen that in diode emulation mode, whenever the inductor current reaches zero the SW node will become high impedance. Ringing will occur on this pin as a result of the LC tank circuit formed by the inductor and the parasitic capaci-tance at the node. If this ringing is of concern an additional RC snubber circuit can be added from the switch node to ground.At very light loads, usually below 100 mA, several pulses may be skipped in between switching cycles, effectively reducing the switching frequency and further improving light-load effi-ciency.30030505FIGURE 1. Modes of Operation for LM20143LM20143Design GuideThis section walks the designer through the steps necessaryto select the external components to build a fully functionalpower supply. As with any DC-DC converter numerous trade-offs are possible to optimize the design for efficiency, size, orperformance. These will be taken into account and highlight-ed throughout this discussion. To facilitate component selec-tion discussions the circuit shown in Figure 2 below may beused as a reference. Unless otherwise indicated all formulasassume units of amps (A) for current, farads (F) for capaci-tance, henries (H) for inductance and volts (V) for voltages.30030523FIGURE 2. Typical Application CircuitThe first equation to calculate for any buck converter is duty-cycle. Ignoring conduction losses associated with the FETsand parasitic resistances it can be approximated by:INDUCTOR SELECTION (L)The inductor value is determined based on the operating fre-quency, load current, ripple current, and duty cycle.The inductor selected should have a saturation current ratinggreater than the peak current limit of the device. Keep in mindthe specified current limit does not account for delay of thecurrent limit comparator, therefore the current limit in the ap-plication may be higher than the specified value. To optimizethe performance and prevent the device from entering currentlimit at maximum load, the inductance is typically selectedsuch that the ripple current, ΔiL, is less than 30% of the ratedoutput current. Figure 3, shown below illustrates the switchand inductor ripple current waveforms. Once the input volt-age, output voltage, operating frequency, and desired ripplecurrent are known, the minimum value for the inductor can becalculated by the formula shown below:30030509FIGURE 3. Switch and Inductor Current WaveformsIf needed, slightly smaller value inductors can be used, how-ever, the peak inductor current, IOUT+ Δi L/2, should be keptbelow the peak current limit of the device. In general, the in-ductor ripple current, ΔiL, should be greater than 10% of therated output current to provide adequate current sense infor-mation for the current mode control loop. If the ripple currentin the inductor is too low, the control loop will not have suffi-cient current sense information and can be prone to instability.OUTPUT CAPACITOR SELECTION (COUT)The output capacitor, COUT, filters the inductor ripple currentand provides a source of charge for transient load conditions.A wide range of output capacitors may be used with theLM20143 that provide excellent performance. The best per-formance is typically obtained using ceramic, SP, or OSCONtype chemistries. Typical trade-offs are that the ceramic ca-pacitor provides extremely low ESR to reduce the outputripple voltage and noise spikes, while the SP and OSCONcapacitors provide a large bulk capacitance in a small volumefor transient loading conditions.When selecting the value for the output capacitor the two per-formance characteristics to consider are the output voltageripple and transient response. The output voltage ripple canbe approximated by using the formula shown below.Where, ΔVOUT(V) is the amount of peak to peak voltage rippleat the power supply output, RESR(Ω) is the series resistanceof the output capacitor, fSW(Hz) is the switching frequency,and COUT(F) is the output capacitance used in the design.The amount of output ripple that can be tolerated is applica-tion specific; however a general recommendation is to keepthe output ripple less than 1% of the rated output voltage.Keep in mind ceramic capacitors are sometimes preferredbecause they have very low ESR; however, depending onpackage and voltage rating of the capacitor the value of thecapacitance can drop significantly with applied voltage. Theoutput capacitor selection will also affect the output voltagedroop during a load transient. The peak droop on the outputvoltage during a load transient is dependent on many factors;however, an approximation of the transient droop ignoringloop bandwidth can be obtained using the following equation.12LM2143Where, COUT(F) is the minimum required output capacitance,L (H) is the value of the inductor, VDROOP(V) is the outputvoltage drop ignoring loop bandwidth considerations, ΔIOUT-STEP(A) is the load step change, RESR(Ω) is the outputcapacitor ESR, VIN(V) is the input voltage, and VOUT(V) isthe set regulator output voltage. Both the tolerance and volt-age coefficient of the capacitor needs to be examined whendesigning for a specific output ripple or transient drop target.INPUT CAPACITOR SELECTION (CIN)Good quality input capacitors are necessary to limit the ripplevoltage at the VIN pin while supplying most of the switch cur-rent during the on-time. In general it is recommended to usea ceramic capacitor for the input as they provide both a lowimpedance and small footprint. One important note is to usea good dielectric for the ceramic capacitor such as X5R orX7R. These provide better over temperature performanceand also minimize the DC voltage derating that occurs on Y5Vcapacitors. For most applications, a 22 µF, X5R, 6.3V inputcapacitor is sufficient; however, additional capacitance maybe required if the connection to the input supply is far from thePVIN pins. The input capacitor should be placed as close aspossible PVIN and PGND pins of the device.Non-ceramic input capacitors should be selected for RMScurrent rating and minimum ripple voltage. A good approxi-mation for the required ripple current rating is given by therelationship:As indicated by the RMS ripple current equation, highest re-quirement for RMS current rating occurs at 50% duty cycle.For this case, the RMS ripple current rating of the input ca-pacitor should be greater than half the output current. For bestperformance, low ESR ceramic capacitors should be placedin parallel with higher capacitance capacitors to provide thebest input filtering for the device.SETTING THE OUTPUT VOLTAGE (RFB1, RFB2)The resistors RFB1and RFB2are selected to set the outputvoltage for the device. Table 1, shown below, provides sug-gestions for RFB1and RFB2for common output voltages.TABLE 1. Suggested Values for RFB1and RFB2RFB1(kΩ)RFB2(kΩ)V OUTshort open0.84.9910 1.28.8710.2 1.512.710.2 1.821.510.2 2.531.610.2 3.3If different output voltages are required, RFB2should be se-lected to be between 4.99 kΩ to 49.9 kΩ and RFB1can becalculated using the equation below.ADJUSTING THE OPERATING FREQUENCY (RT)The operating frequency of the LM20143 can be adjusted byconnecting a resistor from the RT pin to ground. The equationshown below can be used to calculate the value of RTfor agiven operating frequency.Where, fSWis the switching frequency in kHz, and RTis thefrequency adjust resistor in kΩ. Please refer to the curve Os-cillator Frequency verses RTin the typical performance char-acteristics section. If the RTresistor is omitted the device willnot operate.LOOP COMPENSATION (RC1, CC1)The purpose of loop compensation is to meet static and dy-namic performance requirements while maintaining adequatestability. Optimal loop compensation depends on the outputcapacitor, inductor, load, and the device itself. Table 2 belowgives values for the compensation network that will result ina stable system when using a 100 µF, 6.3V ceramic X5R out-put capacitor and 1 µH inductor.TABLE 2.

The overall loop transfer function is the prod-uct of the power stage and the feedback network transferfunctions. For stability purposes, the objective is to have aloop gain slope that is -20db/decade from a very low frequen-cy to beyond the crossover frequency.

LM101A/LM201A/LM301A Operational AmplifiersGeneral DescriptionThe LM101A series are general purpose operational amplifi-ers which feature improved performance over industry stan-dards like the LM709.Advanced processing techniques make possible an order of magnitude reduction in input cur-rents,and a redesign of the biasing circuitry reduces the temperature drift of input current.Improved specifications in-clude:•Offset voltage 3mV maximum over temperature (LM101A/LM201A)•Input current 100nA maximum over temperature (LM101A/LM201A)•Offset current 20nA maximum over temperature (LM101A/LM201A)•Guaranteed drift characteristics•Offsets guaranteed over entire common mode and sup-ply voltage ranges•Slew rate of 10V/µs as a summing amplifierThis amplifier offers many features which make its appli-cation nearly foolproof:overload protection on the inputand output,no latch-up when the common mode range is exceeded,and freedom from oscillations and compensa-tion with a single 30pF capacitor.It has advantages over internally compensated amplifiers in that the frequency compensation can be tailored to the particular applica-tion.For example,in low frequency circuits it can be over-compensated for increased stability margin.Or the com-pensation can be optimized to give more than a factor of ten improvement in high frequency performance for most applications.In addition,the device provides better accuracy and lower noise in high impedance circuitry.The low input currents also make it particularly well suited for long interval inte-grators or timers,sample and hold circuits and low fre-quency waveform generators.Further,replacing circuits where matched transistor pairs buffer the inputs of con-ventional IC op amps,it can give lower offset voltage and a drift at a lower cost.The LM101A is guaranteed over a temperature range of −55˚C to +125˚C,the LM201A from −25˚C to +85˚C,and the LM301A from 0˚C to +70˚C.Connection Diagrams(Top View)Dual-In-Line

placed in series with the input lead to limit the peak instantaneous output current of the source to something less than 100mA.This is especially important when the inputs go outside a piece of equipment where they could accidentally be connected to high voltage rge capacitors on the input (greater than 0.1µF)should be treated as a low source impedance and isolated with a resis-tor.Low impedance sources do not cause a problem unless their output voltage exceeds the supply voltage.However,the supplies go to zero when they are turned off,so the iso-lation is usually needed.The output circuitry is protected against damage from shorts to ground.However,when the amplifier output is connected to a test point,it should be isolated by a limiting resistor,as test points frequently get shorted to bad places.Further,when the amplifer drives a load external to the equipment,it is also advisable to use some sort of limiting resistance to preclude mishaps.Precautions should be taken to insure that the power sup-plies for the integrated circuit never become reversed —even under transient conditions.With reverse voltages greater than 1V,the IC will conduct excessive cur-rent,fusing internal aluminum interconnects.If there is a possibility of this happening,clamp diodes with a high peak current rating should be installed on the supply lines.Rever-sal of the voltage between V +and V −will always cause a problem,although reversals with respect to ground may also give difficulties in many circuits.The minimum values given for the frequency compensation capacitor are stable only for source resistances less than 10k Ω,stray capacitances on the summing junction less than 5pF and capacitive loads smaller than 100pF.If any of these conditions are not met,it becomes necessary to over-compensate the amplifier with a larger compensation capaci-tor.Alternately,lead capacitors can be used in the feedback network to negate the effect of stray capacitance and large feedback resistors or an RC network can be added to isolate capacitive loads.Although the LM101A is relatively unaffected by supply by-passing,this cannot be ignored altogether.Generally it is necessary to bypass the supplies to ground at least once on every circuit card,and more bypass points may be required if more than five amplifiers are used.When feed-forward compensation is employed,however,it is advisable to by-pass the supply leads of each amplifier with low inductance capacitors because of the higher frequencies involved.Typical Applications(Note 9)Standard Compensation and Offset Balancing

LM101A/LM201A/LM301A Operational AmplifiersGeneral DescriptionThe LM101A series are general purpose operational amplifi-ers which feature improved performance over industry stan-dards like the LM709.Advanced processing techniques make possible an order of magnitude reduction in input cur-rents,and a redesign of the biasing circuitry reduces the temperature drift of input current.Improved specifications in-clude:•Offset voltage 3mV maximum over temperature (LM101A/LM201A)•Input current 100nA maximum over temperature (LM101A/LM201A)•Offset current 20nA maximum over temperature (LM101A/LM201A)•Guaranteed drift characteristics•Offsets guaranteed over entire common mode and sup-ply voltage ranges•Slew rate of 10V/µs as a summing amplifierThis amplifier offers many features which make its appli-cation nearly foolproof:overload protection on the inputand output,no latch-up when the common mode range is exceeded,and freedom from oscillations and compensa-tion with a single 30pF capacitor.It has advantages over internally compensated amplifiers in that the frequency compensation can be tailored to the particular applica-tion.For example,in low frequency circuits it can be over-compensated for increased stability margin.Or the com-pensation can be optimized to give more than a factor of ten improvement in high frequency performance for most applications.In addition,the device provides better accuracy and lower noise in high impedance circuitry.The low input currents also make it particularly well suited for long interval inte-grators or timers,sample and hold circuits and low fre-quency waveform generators.Further,replacing circuits where matched transistor pairs buffer the inputs of con-ventional IC op amps,it can give lower offset voltage and a drift at a lower cost.The LM101A is guaranteed over a temperature range of −55˚C to +125˚C,the LM201A from −25˚C to +85˚C,and the LM301A from 0˚C to +70˚C.Connection Diagrams(Top View)Dual-In-Line

It has advantages over internally com-pensated amplifiers in that the compensation can be tailored to the particular application: slew rate of 10V/µs and bandwidth of 3.5MHz can be easily achieved.ORDER CODEN = Dual in Line Package (DIP)D = Small Outline Package (SO) - also available in Tape & Reel (DT)PIN CONNECTIONS (top view)Part Number Temperature Range Package N D LM101A -55°C, +125°C ••LM201A -40°C, +105°C ••LM301A 0°C, +70°C ••Example :LM201ANLM101A-LM201ALM301ASINGLE OPERATIONAL AMPLIFIERSDecember 2001LM101A - LM201A - LM301A2/11SCHEMATIC DIAGRAMABSOLUTE MAXIMUM RATINGSSymbol ParameterLM101ALM201A LM301AUnit V CC Supply voltage ±22V V i Input Voltage±15V V id Differential Input Voltage ±30V P tot Power DissipationN Suffix D Suffix500300mW Output Short-circuit DurationInfinite T oper Opearting Free-air Temperature Range -55 to +125-40 to +1050 to +70°C T stgStorage Temperature Range-65 to +150°CLM101A - LM201A - LM301A3/11ELECTRICAL CHARACTERISTICS±5V ≤ V CC ≤ ±20V, C1 = 30pF, T amb = 25°C (unless otherwise specified)SymbolParameterLM101A - LM201ALM301AUnitMin.Typ.Max.Min.Typ.Max.V io Input Offset Voltage (R S ≤ 10k Ω) T amb = +25°CT min ≤ T amb ≤ T max 0.72327.510mVDV io Input Offset Voltage DriftT min ≤ T amb ≤ T max 315630µV/°CI ibInput Bias Current - noteT amb = +25°CT min ≤ T amb ≤ T max 257510070250300nAI ioInput Offset Current T amb = +25°CT min ≤ T amb ≤ T max 1.5102025070nADI IioInput Offset Current DriftT min ≤ T amb ≤ 25°C T min ≤ T amb ≤ T max 10201002001020300600pA/°CA vdLarge Signal Voltage Gain *V O ≤ 10V, R L = 2k Ω)T amb = +25°CT min ≤ T amb ≤ T max50251002515100V/mVSVR Supply Voltage Rejection Ratio (R s ≤ 10k Ω)T amb = +25°CT min ≤ T amb ≤ T max 808096707096dBI CCSupply Current, no load T amb = +25°CT min ≤ T amb ≤ T max1.8331.833mAV icmInput Common Mode Voltage Range (V CC = ±20V)T amb = +25°CT min ≤ T amb ≤ T max±15±15±15±15VCMR Common Mode Rejection Ratio (R s ≤ 10k Ω)T amb = +25°CT min ≤ T amb ≤ T max 808096707096dBI OSOutput Short-circuit Current * T amb = +25°C 103050103050mA±V OPPOutput Voltage Swing *T amb = +25°CR L = 10k Ω R L = 2k ΩT min ≤ T amb ≤ T maxR L = 10k Ω R L = 2k Ω121012101413121012101413VSRSlew Rate (V i = ±10V, R L = 2k Ω,C L = 100pF,unity gain) - 1)0.250.50.250.5V/µsLM101A - LM201A - LM301A4/11t rRise (V i = ±20mV, R L = 2k Ω,C L = 100pF, unity gain)0.30.3µs K OV Overshoot (V i = 20mV, R L = 2k Ω,C L = 100pF, unity gain)55%Z i Input Impedance *1.54 1.54M ΩGBPGain Bandwidth Product *(V i = 10mV, R L = 2k Ω,C L = 100pF, f = 100KHz)0.510.51MHzTHDTotal Harmonic Distortion(f = 1kHz, A v = 20dB, R L = 2k Ω, V o = 2V pp ,C L = 100pF)0.0150.015%e nEquivalent Input Noise Voltage f = 1kHz, R s = 100Ω25251.May be improved up to 10V/µs in inverting amplifier configuration * ==> V CC = ±15V, T amb = +25°C (unless otherwise specified)SymbolParameterLM101A - LM201ALM301AUnitMin.Typ.Max.Min.Typ.Max.nV Hz-----------LM101A - LM201A - LM301A5/11LM101A - LM201A - LM301A6/11SINGLE POLE COMPENSATIONFEED FORWARD COMPENSATIONLM101A - LM201A - LM301A7/11LM101A - LM201A - LM301A8/11LM101A - LM201A - LM301A9/11LM101A - LM201A - LM301A10/11PACKAGE MECHANICAL DATA 8 PINS - PLASTIC DIPlimetersInches Min.Typ.Max.Min.Typ.Max.A 3.320.131a10.510.020B 1.15 1.650.0450.065b 0.3560.550.0140.022b10.2040.3040.0080.012D 10.920.430E 7.959.750.3130.384e 2.540.100e37.620.300e47.620.300F 6.60260i 5.080.200L 3.18 3.810.1250.150Z1.520.060LM101A - LM201A - LM301A11/11PACKAGE MECHANICAL DATA8 PINS - PLASTIC MICROPACKAGE (SO)limetersInches Min.Typ.Max.Min.Typ.Max.A 1.750.069a10.10.250.0040.010a2 1.650.065a30.650.850.0260.033b 0.350.480.0140.019b10.190.250.0070.010C 0.250.50.0100.020c145° (typ.)D 4.8 5.00.1890.197E 5.86.20.2280.244e 1.270.050e3 3.810.150F 3.8 4.00.1500.157L 0.41.270.0160.050M 0.60.024S8° (max.)Information furnished is believed to be accurate and reliable.

TL H 7752LM101A LM201A LM301A Operational AmplifiersDecember1994LM101A LM201A LM301A Operational AmplifiersGeneral DescriptionThe LM101A series are general purpose operational amplifi-ers which feature improved performance over industry stan-dards like the LM709 Advanced processing techniquesmake possible an order of magnitude reduction in input cur-rents and a redesign of the biasing circuitry reduces thetemperature drift of input current Improved specificationsincludeY Offset voltage3mV maximum overtemperature(LM101A LM201A)Y Input current100nA maximum overtemperature(LM101A LM201A)Y Offset current20nA maximum overtemperature(LM101A LM201A)Y Guaranteed drift characteristicsY Offsets guaranteed over entire common mode and sup-ply voltage rangesY Slew rate of10V m s as a summing amplifierThis amplifier offers many features which make its applica-tion nearly foolproof overload protection on the input andoutput no latch-up when the common mode range is ex-ceeded and freedom from oscillations and compensationwith a single30pF capacitor It has advantages over inter-nally compensated amplifiers in that the frequency compen-sation can be tailored to the particular application For ex-ample in low frequency circuits it can be overcompensatedfor increased stability margin Or the compensation can beoptimized to give more than a factor of ten improvement inhigh frequency performance for most applicationsIn addition the device provides better accuracy and lowernoise in high impedance circuitry The low input currentsalso make it particularly well suited for long interval integra-tors or timers sample and hold circuits and low frequencywaveform generators Further replacing circuits wherematched transistor pairs buffer the inputs of conventional ICop amps

H 7752–28Although the LM101A is designed for trouble free operation experience has indicated that it is wise to observe certain precautions given below to protect the devices from abnor-mal operating conditions It might be pointed out that the advice given here is applicable to practically any IC op amp although the exact reason why may differ with different de-vicesWhen driving either input from a low-impedance source a limiting resistor should be placed in series with the input lead to limit the peak instantaneous output current of the source to something less than100mA This is especially important when the inputs go outside a piece of equipment where they could accidentally be connected to high voltage sources Large capacitors on the input(greater than0 1m F) should be treated as a low source impedance and isolated with a resistor Low impedance sources do not cause a problem unless their output voltage exceeds the supply volt-age However the supplies go to zero when they are turned off so the isolation is usually neededThe output circuitry is protected against damage from shorts to ground However when the amplifier output is connected to a test point it should be isolated by a limiting resistor as test points frequently get shorted to bad places Further when the amplifer drives a load external to the equipment it is also advisable to use some sort of limiting resistance to preclude mishaps Precautions should be taken to insure that the power sup-plies for the integrated circuit never become reversed even under transient conditions With reverse voltages greater than1V the IC will conduct excessive current fus-ing internal aluminum interconnects If there is a possibility of this happening clamp diodes with a high peak current rating should be installed on the supply lines Reversal of the voltage between V a and V b will always cause a prob-lem although reversals with respect to ground may also give difficulties in many circuitsThe minimum values given for the frequency compensation capacitor are stable only for source resistances less than 10k X stray capacitances on the summing junction less than5pF and capacitive loads smaller than100pF If any of these conditions are not met it becomes necessary to overcompensate the amplifier with a larger compensation capacitor Alternately lead capacitors can be used in the feedback network to negate the effect of stray capacitance and large feedback resistors or an RC network can be add-ed to isolate capacitive loadsAlthough the LM101A is relatively unaffected by supply by-passing this cannot be ignored altogether Generally it is necessary to bypass the supplies to ground at least once on every circuit card and more bypass points may be required if more than five amplifiers are used When feed-forward compensation is employed however it is advisable to by-pass the supply leads of each amplifier with low inductance capacitors because of the higher frequencies
