LM118/LM218/LM318 Operational Amplifiers General DescriptionThe LM118series are precision high speed operational am-plifiers designed for applications requiring wide bandwidth and high slew rate.They feature a factor of ten increase in speed over general purpose devices without sacrificing DC performance.The LM118series has internal unity gain frequency compen-sation.This considerably simplifies its application since no external components are necessary for operation.However, unlike most internally compensated amplifiers,external fre-quency compensation may be added for optimum perfor-mance.For inverting applications,feedforward compensa-tion will boost the slew rate to over150V/µs and almost double the bandwidth.Overcompensation can be used with the amplifier for greater stability when maximum bandwidth is not needed.Further,a single capacitor can be added to reduce the0.1%settling time to under1µs.The high speed and fast settling time of these op amps make them useful in A/D converters,oscillators,active filters,sample and hold circuits,or general purpose amplifiers. These devices are easy to apply and offer an order of magnitude better AC performance than industry standards such as the LM709.The LM218is identical to the LM118except that the LM218 has its performance specified over a−25˚C to+85˚C tem-perature range.The LM318is specified from0˚C to+70˚C.

based on a thermal resistance of 160˚C/W,junction to ambient,or 20˚C/W,junction to case.The thermal resistance of the dual-in-line package is 100˚C/W,junction to ambient.Note 3:The inputs are shunted with back-to-back diodes for overvoltage protection.Therefore,excessive current will flow if a differential input voltage in excess of 1V is applied between the inputs unless some limiting resistance is used.Note 4:For supply voltages less than ±15V,the absolute maximum input voltage is equal to the supply voltage.Note 5:These specifications apply for ±5V ≤V S ≤±20V and −55˚C ≤T A ≤+125˚C (LM118),−25˚C ≤T A ≤+85˚C (LM218),and 0˚C ≤T A ≤+70˚C (LM318).Also,power supplies must be bypassed with 0.1µF disc capacitors.Note 6:Slew rate is tested with V S =±15V.The LM118is in a unity-gain non-inverting configuration.V IN is stepped from −7.5V to +7.5V and vice versa.The slew rates between −5.0V and +5.0V and vice versa are tested and guaranteed to exceed 50V/µs.Note 7:Refer to RETS118X

NOTES: 1. This rating applies for ±15V supplies. The positive input voltage limit is 30V above the negative supply. The negative input voltage limit is equal to the negative supply voltage or 30V below the positive supply, whichever is less. 2. These specifications apply for VS=±15V and 0°C < TA < 70°C unless otherwise specified. With the LM211, however, all temperature specifications are limited to -25°C ≤ TA ≤ 85°C and for the LM111 is limited to -55°C TA < 125°C. The offset voltage, offset current, and bias current specifications apply for any supply voltage from a single 5V supply up to ±15V supplies. 3. The offset voltages and offset currents given are the maximum values required to drive the output within a volt of either supply with 1mA load. Thus, these parameters define an error band and take into account the worst case effects of voltage gain and input impedance. 4. The response time specified is for a 100mV input step with 5mV over-drive. 5. Do not short the strobe pin to ground; it should be current driven at 3mA to 5mA. 6. LM311B, all parameters are at V+ = 3V ±10%, V– = GND = 0V.

High slew rate operational amplifier
NE/SE531
DESCRIPTION
The 531 is a fast slewing high performance operational amplifier which retains DC performance equal to the best general purpose types while providing far superior large-signal AC performance. A unique input stage design allows the amplifier to have a large-signal response nearly identical to its small-signal response. The amplifier is compensated for truly negligible overshoot with a single capacitor. In applications where fast settling and superior large-signal bandwidths are required, the amplifier out-performs conventional designs which have much better small-signal response. Also, because the small-signal response is not extended, no special precautions need be taken with circuit board layout to achieve stability. The high gain, simple compensation, and excellent stability of this amplifier allow its use in a wide variety of instrumentation applications.

Voltage comparator
LM111/211/311/ LM311B
DESCRIPTION
The LM111 series are voltage comparators that have input currents approximately a hundred times lower than devices like the µA710. They are designed to operate over a wider range of supply voltages; from standard ±15V op amp supplies down to a single 3V supply. Their output is compatible with RTL, DTL, and TTL as well as MOS circuits. Further, they can drive lamps or relays, switching voltages up to 50V at currents as high as 50mA. Both the inputs and the outputs of the LM111 series can be isolated from system ground, and the output can drive loads referred to ground, the positive supply, or the negative supply. Offset balancing and strobe capability are provided and outputs can be wire-ORed. Although slower than the µA710 (200ns response time vs 40ns), the devices are also much less prone to spurious oscillations. The LM111 series has the same pin configuration as the µA710 series.

Highly Flexible Voltage Comparators
The ability to operate from a single power supply of 5.0 V to 30 V or ±15 V split supplies, as commonly used with operational amplifiers, makes the LM211/LM311 a truly versatile comparator. Moreover, the inputs of the device can be isolated from system ground while the output can drive loads referenced either to ground, the VCC or the VEE supply. This flexibility makes it possible to drive DTL, RTL, TTL, or MOS logic. The output can also switch voltages to 50 V at currents to 50 mA. Thus the LM211/LM311 can be used to drive relays, lamps or solenoids.

IRMCK311 is designed to achieve low cost and high performance control solutions for advanced inverterized appliance motor control. IRMCK311 contains two computation engines. One is Motion Control Engine (MCE TM) for sensorless control of permanent magnet motors; the other is an 8-bit high-speed microcontroller (8051). Both computation engines are integrated into one monolithic chip. The MCE TM contains a collection of control elements such as Proportional plus Integral, Vector rotator, Angle estimator, Multiply/Divide, Low loss SVPWM, Single Shunt IFB. The user can program a motion control algorithm by connecting these control elements using a graphic compiler. Key components of the sensorless control algorithms, such as the Angle Estimator, are provided as complete pre-defined control blocks implemented in hardware. A unique analog/digital circuit and algorithm to fully support single shunt current reconstruction is also provided. The 8051 microcontroller performs 2-cycle instruction execution (16MIPS at 33MHz). The MCE and 8051 microcontroller are connected via dual port RAM to process signal monitoring and command input. An advanced graphic compiler for the MCE TM is seamlessly integrated into the MATLAB/Simulink environment, while third party JTAG based emulator tools are supported for 8051 developments. IRMCK311 comes with a small QFP64 pin lead-free package.TABLE OF CONTENTS1 Overview (5)2 IRMCK311 Block Diagram and Main Functions (6)3 Pinout (8)4 Input/Output of IRMCK311 (9)4.1 8051 Peripheral Interface Group (10)4.2 Motion Peripheral Interface Group (10)4.3 Analog Interface Group (11)4.4 Power Interface Group (11)4.5 Test Interface (12)5 Application Connections (13)6 DC Characteristics (14)6.1 Absolute Maximum Ratings (14)6.2 System Clock Frequency and Power Consumption (14)6.3 Digital I/O DC Characteristics (15)6.4 PLL and Oscillator DC Characteristics (15)6.5 Analog I/O DC Characteristics (16)6.6 Under Voltage Lockout DC Characteristics (17)6.7 AREF Characteristics (17)7 AC Characteristics (18)7.1 PLL AC Characteristics (18)7.2 Analog to Digital Converter AC Characteristics (19)7.3 Op Amp AC Characteristics (19)7.4 SYNC to SVPWM and A/D Conversion AC Timing (20)7.5 GATEKILL to SVPWM AC Timing (21)7.6 Interrupt AC Timing (21)7.7 I2C AC Timing (22)7.8 SPI AC Timing (23)7.8.1 SPI Write AC timing (23)7.8.2 SPI Read AC Timing (24)7.9 UART AC Timing (25)7.10 CAPTURE Input AC Timing (26)7.11 JTAG AC Timing (27)7.12 OTP Programming Timing (28)8 I/O Structure (29)9 Pin List (32)Dimensions (35)10 Package11 Part Marking Information (36)Information (36)12 OrderingTABLE OF FIGURESFigure 1.

Pin List (32)1 OverviewIRMCK311 is a new International Rectifier integrated circuit device primarily designed as a one-chip solution for complete inverter controlled appliance dual motor control applications. Unlike a traditional microcontroller or DSP, the IRMCK311 provides a built-in closed loop sensorless control algorithm using the unique Motion Control Engine (MCE TM) for permanent magnet motors. The MCE TM consists of a collection of control elements, motion peripherals, a dedicated motion control sequencer and dual port RAM to map internal signal nodes. IRMCK311 also employs a unique single shunt current reconstruction circuit to eliminate additional analog/digital circuitry and enables a direct shunt resistor interface to the IC. The sensorless control is the same for both motors with a single shunt current sensing capability. Motion control programming is achieved using a dedicated graphical compiler integrated into the MATLAB/Simulink TM development environment. Sequencing, user interface, host communication, and upper layer control tasks can be implemented in the 8051 high-speed 8-bit microcontroller. The 8051 microcontroller is equipped with a JTAG port to facilitate emulation and debugging tools. Figure 1 shows a typical application schematic using IRMCK311.IRMCK311 is intended for volume production purpose and contains 64K bytes of OTP (One Time Programming) ROM, which can be programmed through a JTAG port. For a development purpose use, IRMCF311 contains a 48k byte of RAM in place of program OTP to facilitate an application development work. Both IRMCF311 and IRMCK311 come in the same 64-pin QFP package with identical pin configuration to facilitate PC board layout and transition to mass productionFigure 1.

Hints8.1CIRCUIT TECHNIQUES FOR AVOIDINGOSCILLATIONS IN COMPARATOR APPLICATIONSWhen a high-speed comparator such as the LM111is used with fast input signals and low source impedances,the out-put response will normally be fast and stable,assuming that the power supplies have been bypassed (with 0.1µF disc capacitors),and that the output signal is routed well away from the inputs (pins 2and 3)and also away from pins 5and 6.However,when the input signal is a voltage ramp or a slow sine wave,or if the signal source impedance is high (1k Ωto 100k Ω),the comparator may burst into oscillation near the crossing-point.This is due to the high gain and wide band-width of comparators like the LM111.To avoid oscillation or instability in such a usage,several precautions are recom-mended,as shown in Figure 1below.1.The trim pins (pins 5and 6)act as unwanted auxiliaryinputs.If these pins are not connected to a trim-pot,they should be shorted together.If they are connected to a trim-pot,a 0.01µF capacitor C1between pins 5and 6will minimize the susceptibility to AC coupling.A smaller capacitor is used if pin 5is used for positive feedback as in Figure 1.2.Certain sources will produce a cleaner comparator out-put waveform if a 100pF to 1000pF capacitor C2is connected directly across the input pins.3.When the signal source is applied through a resistivenetwork,R S ,it is usually advantageous to choose an R S 'of substantially the same value,both for DC and for dynamic (AC)considerations.Carbon,tin-oxide,and metal-film resistors have all been used successfully in comparator input circuitry.Inductive wirewound resistors are not suitable.4.When comparator circuits use input resistors (eg.sum-ming resistors),their value and placement are particu-larly important.In all cases the body of the resistor should be close to the device or socket.In other words there should be very little lead length or printed-circuit foil run between comparator and resistor to radiate or pick up signals.The same applies to capacitors,pots,etc.For example,if R S =10k Ω,as little as 5inches oflead between the resistors and the input pins can result in oscillations that are very hard to damp.Twisting these input leads tightly is the only (second best)alternative to placing resistors close to the comparator.5.Since feedback to almost any pin of a comparator canresult in oscillation,the printed-circuit layout should be engineered thoughtfully.Preferably there should be a groundplane under the LM111circuitry,for example,one side of a double-layer circuit card.Ground foil (or,posi-tive supply or negative supply foil)should extend be-tween the output and the inputs,to act as a guard.The foil connections for the inputs should be as small and compact as possible,and should be essentially sur-rounded by ground foil on all sides,to guard against capacitive coupling from any high-level signals (such as the output).If pins 5and 6are not used,they should be shorted together.If they are connected to a trim-pot,the trim-pot should be located,at most,a few inches away from the LM111,and the 0.01µF capacitor should be installed.If this capacitor cannot be used,a shielding printed-circuit foil may be advisable between pins 6and 7.The power supply bypass capacitors should be lo-cated within a couple inches of the LM111.(Some other comparators require the power-supply bypass to be lo-cated immediately adjacent to the comparator.)6.It is a standard procedure to use hysteresis (positivefeedback)around a comparator,to prevent oscillation,and to avoid excessive noise on the output because the comparator is a good amplifier for its own noise.In the circuit of Figure 2,the feedback from the output to the positive input will cause about 3mV of hysteresis.How-ever,if R S is larger than 100Ω,such as 50k Ω,it would not be reasonable to simply increase the value of the positive feedback resistor above 510k Ω.The circuit of Figure 3could be used,but it is rather awkward.See the notes in paragraph 7below.L M 111/L M 211/L M 311108.0Application Hints(Continued)7.When both inputs of the LM111are connected to activesignals,or if a high-impedance signal is driving the positive input of the LM111so that positive feedback would be disruptive,the circuit of Figure1is ideal.The positive feedback is to pin5(one of the offset adjust-ment pins).It is sufficient to cause1to2mV hysteresis and sharp transitions with input triangle waves from a few Hz to hundreds of kHz.The positive-feedback signal across the82Ωresistor swings240mV below the posi-tive supply.This signal is centered around the nominal voltage at pin5,so this feedback does not add to the V OS of the comparator.As much as8mV of V OS can be trimmed out,using the5kΩpot and3kΩresistor as shown.8.These application notes apply specifically to the LM111,LM211,LM311,and LF111families of comparators,and are applicable to all high-speed comparators in general, (with the exception that not all comparators have trim pins).00570429Pin connections shown are for LM111H in the H08hermetic packageFIGURE1.Improved Positive Feedback00570430 Pin connections
