If the inputs go beyond either supply rail, the input current should be limited to less than 10mA.Note 3: The LTC6401C and LTC6401I are guaranteed functional over the operating temperature range of –40°C to 85°CNote 4: The LTC6401C is guaranteed to meet specifi ed performance from 0°C to 70°C. It is designed, characterized and expected to meet specifi ed performance from –40°C to 85°C but is not tested or QA sampled at these temperatures. The LTC6401I is guaranteed to meet specifi ed performance from –40°C to 85°C.Note 5: Input and output baluns used. See Test Circuit A.Note 6: Measured using Test Circuit B. R L = 87.5Ω per output.Note 7: Since the LTC6401-26 is a feedback amplifi er with low output impedance, a resistive load is not required when driving an AD converter. Therefore, typical output power is very small.

Differential gain and input impedance are set by 25Ω/500Ω resistors in the feedback network. Small output resistors of 12.5Ω improve the circuit stability over various load conditions. They also provide a possible external fi ltering option, which is often desirable when the load is an ADC.Filter resistors of 50Ω are available for additional fi ltering. Lowpass/bandpass fi lters are easily implemented with just a couple of external components. Moreover, they offer single-ended 50Ω matching in wideband applications and no external resistor is needed.The LTC6401-26 is very fl exible in terms of I/O coupling. It can be AC- or DC-coupled at the inputs, the outputs or both. Due to the internal connection between input and output, users are advised to keep input common mode voltage between 1V and 1.6V for proper operation. If the inputs are AC-coupled, the input common mode voltage is automatically biased close to V OCM and thus no external circuitry is needed for bias. The LTC6401-26 provides an output common mode voltage set by V OCM, which allows driving ADC directly without external components such as transformer or AC coupling capacitors. The input signal can be either single-ended or differential with only minor difference in distortion performance.Input Impedance and MatchingThe differential input impedance of the LTC6401-26 is 50Ω. The interface between the input of LTC6401-26 and 50Ωsource is straightforward. One way is to directly connect them if the source is differential (Figure 1). Another ap-proach is to employ a wideband transformer if the source is single ended (Figure 2). Both methods provide a wide-band match. Alternatively, one could apply a narrowband impedance match at the inputs of the LTC6401-26 for frequency selection and/or noise reduction.Referring to F igure 3, LTC6401-26 can be easily confi gured for single-ended input and differential output without a balun. The signal is fed to one of the inputs through a matching network while the other input is connected to the same matching network and a source resistor. Because the return ratios of the two feedback paths are equal, the two outputs have the same gain and thus symmetrical swing. In general, the single-ended input impedance and termination resistor R T are determined by the combination of R S, R G and R F. For example, when R S is 50Ω, it is found that the single-ended input impedance is 75Ω and R T is 150Ω in order to match to a 50Ω source impedance.Figure 1. Input Termination for Differential 50Ω Input ImpedanceFigure 2. Input Termination for Differential 50Ω Input Impedance Using a Balun10640126f11640126fThe LTC6401-26 is unconditionally stable, i.e. differential stability factor Kf>1 and stability measure B1>0. However, the overall differential gain is affected by both source impedance and load impedance as shown in Figure 4:A V V R R R V OUT IN S L L==++10005025•The noise performance of the LTC6401-26 also dependsupon the source impedance and termination. A trade-off between gain and noise is obvious when constant noise fi gure circle and constant gain circle are plotted within the same input Smith Chart, based on which users can choose the optimal source impedance for a given gain and noise requirement.Output Impedance Match and FilterThe LTC6401-26 can drive an ADC directly without external output impedance matching. Alternatively, the differential output impedance of 25Ω can be made larger, e.g. 50Ω, by series resistors or LC network.Figure 4. Calculate Differential GainAPPLICATIONS INFORMATIONFigure 3. Input Termination for Single-Ended 50Ω Input ImpedanceThe internal low pass fi lter outputs at +OUTF/–OUTF have a –3dB bandwidth of 590MHz. External capacitors can reduce the low pass fi lter bandwidth as shown in Figure 5. A bandpass fi lter is easily implemented with only a few components as shown in Figure 6. Three 39pF ca-pacitors and 16nH inductor create a bandpass fi lter with 165MHz center frequency, –3dB frequencies at 138MHz and 200MHz.Output Common Mode AdjustmentThe LTC6401-26’s output common mode voltage is set by the V OCM pin, which is a high impedance input. The output common mode voltage is capable of tracking V OCM in a range from 1V to 1.6V. Bandwidth of V OCM control is typically 15MHz, which is dominated by a low pass fi lter connected to the V OCM pin and is aimed to reduce com-mon mode noise generation at the outputs. The internal common mode feedback loop has a –3dB bandwidth of 400MHz, allowing fast rejection of any common mode output voltage disturbance. The V OCM pin should be tied to a DC bias voltage with a 0.1μF bypass capacitor. When interfacing with 3V A/D converters such as the LTC22xx families, the V OCM pin can be connected to the V CM pin of the ADC.Driving A/D ConvertersThe LTC6401-26 has been specifi cally designed to interface directly with high speed A/D converters. F igure 7 shows the LTC6401-26 with single-ended input driving the LTC2208, which is a 16-bit, 130Msps ADC. Two external 5Ω resistors help eliminate potential resonance associated with bond wires of either the ADC input or the driver output. V OCMFigure 5.

Alternatively, a single-ended input signal can be converted to a differential signal via a balun and fed to the input of the LTC6401-26. Figure 8 summarizes the IMD3 performance of the whole system as shown in Figure 7. Test CircuitsDue to the fully-differential design of the LTC6401 and its usefulness in applications with differing characteristic specifi cations, two test circuits are used to generate the information in this datasheet. Test Circuit A is DC987B, a two-port demonstration circuit for the LTC6401 family. The silkscreen is shown in Figure 9. This circuit includes input and output transformers (baluns) for single-ended-to-differential conversion and impedance transformation, allowing direct hook-up to a 2-port network analyzer. There are also series resistors at the output to present the LTC6401 with a 375Ω differential load, optimizing distortion performance. Due to the input and output transformers, the –3dB bandwidth is reduced from 1.6GHz to 1.37GHz.Test Circuit B uses a 4-port network analyzer to measure S-parameters and gain/phase response. This removes the effects of the wideband baluns and associated circuitry, for a true picture of the >1GHz S-parameters and AC characteristics.APPLICATIONS INFORMATIONFigure 9.

Open drain output that goes high impedance when the external MOSFET is on and the circuit breaker is armed. Otherwise this pin pulls low.ON (Pin 2): ON Control Input. The LTC4213 is in reset mode when the ON pin is below 0.4V. When the ON pin increases above 0.8V, the device starts up and the GATE pulls up with a 100µA current source. When the ON pin drops below 0.76V, the GATE pulls down. To reset a circuit breaker fault, the ON pin must go below 0.4V.I SEL (Pin 3): Threshold Select Input. With the I SEL pin grounded, float or tied to V CC the V CB is set to 25mV, 50mV or 100mV, respectively. The corresponding V CB(FAST)values are 100mV, 175mV and 325mV.GND (Pin 4): Device Ground.GATE (P in 5): GATE D rive Output. An internal charge pump supplies 100µA pull-up current to the gate of the external N-channel MOSFET. Internal circuitry limits thevoltage between the GATE and SENSEN pins to a safe gate drive voltage of less than 8V. When the circuit breaker trips, the GATE pin abruptly pulls to GND.SENSEN (Pin 6): Circuit Breaker Negative Sense Input.Connect this pin to the source of the external MOSFET.During reset or fault mode, the SENSEN pin discharges the output to ground with 280µA.SENSEP (P in 7): Circuit Breaker Positive Sense Input.Connect this pin to the drain of external N-channel MOSFET.The circuit breaker trips when the voltage across SENSEP and SENSEN exceeds V CB . The input common mode range of the circuit breaker is from ground to V CC + 0.2V when V CC < 2.5V. For V CC ≥ 2.5V, the input common mode range is from ground to V CC + 0.4V.V CC (Pin 8): Bias Supply Voltage Input. Normal operation is between 2.3V and 6V. An internal under-voltage lockout circuit disables the device when V CC < 2.07V.Exposed Pad (Pin 9): Exposed pad may be left open or connected to device ground.8910114213fsupply transient dips below 1.97V of less than 80µs are ignored.ON FunctionWhen V ON is below comparator COMP1’s threshold of 0.4V for 80µs, the device resets. The system leaves reset mode if the ON pin rises above comparator COMP2’s threshold of 0.8V and the UVLO condition is met. Leaving reset mode, the GATE pin starts up after a t DEBOUNCE delay of 60µs. When ON goes below 0.76V, the GATE shuts off after a 5µs glitch filter delay. The output is discharged by the external load when V ON is in between 0.4V to 0.8V. At this state, the ON pin can re-enable the GATE if V ON exceeds 0.8V for more than 8µs. Alternatively, the device resets if the ON pin is brought below 0.4V for 80µs. Once reset, the GATE pin restarts only after the t DEBOUNCE 60µs delay at V ON rising above 0.8V. To protect the ON pin from overvoltage stress due to supply transients, a series resistor of greater than 10k is recommended when the ON pin is connected directly to the supply. An external resis-tive divider at the ON pin can be used with COMP2 to set a supply undervoltage lockout value higher than the inter-nal UVLO circuit. An RC filter can be implemented at the ON pin to increase the powerup delay time beyond the internal 60µs delay.Gate FunctionThe GATE pin is held low in reset mode. 60µs after leaving reset mode, the GATE pin is charged up by an internal 100µA current source. The circuit breaker arms when V GATE > V SENSEN + ∆V GSARM . In normal mode operation,the GATE peak voltage is internally clamped to ∆V GSMAX above the SENSEN pin. When the circuit breaker trips, an internal MOSFET shorts the GATE pin to GND, turning off the external MOSFET.READY StatusThe READY pin is held low during reset and at startup. It is pulled high by an external pullup resistor 50µs after the circuit breaker arms. The READY pin pulls low if the circuit breaker trips or the ON pin is pulled below 0.76V, or V CC drops below undervoltage lockout.∆V GSARM and V GSMAXEach MOSFET has a recommended V GS drive voltage where the channel is deemed fully enhanced and R DSON is minimized. Driving beyond this recommended V GS volt-age yields a marginal decrease in R DSON . At startup, the gate voltage starts at ground potential. The GATE ramps past the MOSFET threshold and the load current begins to flow. When V GS exceeds ∆V GSARM , the circuit breaker is armed and enabled. The chosen MOSFET should have a recommended minimum V GS drive level that is lower than ∆V GSARM . Finally, V GS reaches a maximum at ∆V GSMAX.Trip and Reset Circuit BreakerFigure 2 shows the timing diagram of V GATE and V READY after a fault condition. A tripped circuit breaker can be reset either by cycling the V CC bias supply below UVLO thresh-old or pulling ON below 0.4V for >t RESET . Figure 3 shows the timing diagram for a tripped circuit breaker being reset by the ON pin.Calculating Current LimitThe fault current limit is determined by the R DSON of the MOSFET and the circuit breaker voltage V CB .I V R LIMIT CB DSON=()2The R DSON value depends on the manufacturer’s distribu-tion, V GS and junction temperature. Short Kelvin-sense connections between the MOSFET drain and source to the LTC4213 SENSEP and SENSEN pins are strongly recommended.For a selected MOSFET, the nominal load limit current is given by:I V R LIMIT NOM CB NOM DSON NOM ()()()()=3The minimum load limit current is given by:I V R LIMIT MIN CB MIN DSON MAX ()()()()=4APPLICATIO S I FOR ATIOW UUU1213144213fOperating temperature of 0° to 70°C.R DSON @ 25°C = 100%R DSON @ 0°C = 90%R DSON @ 70°C = 120%MOSFET resistance variation:R DSON(NOM) = 15m • 0.82 = 12.3m ΩR DSON(MAX) = 15m • 1.333 • 0.93 • 1.2 = 15m • 1.488= 22.3m ΩR DSON(MIN) = 15m • 0.667 • 0.80 • 0.90 = 15m • 0.480= 7.2m ΩV CB variation:NOM V CB = 25mV = 100%MIN V CB = 22.5mV = 90%MAX V CB = 27.5mV = 110%The current limits are:I LIMIT(NOM) = 25mV/12.3m Ω = 2.03A I LIMIT(MIN) = 22.5mV/22.3m Ω = 1.01A I LIMIT(MAX) = 27.5mV/7.2m Ω = 3.82AFor proper operation, the minimum current limit must exceed the circuit maximum operating load current with margin. So this system is suitable for operating load current up to 1A. From this calculation, we can start with the general rule for MOSFET R DSON by assuming maxi-mum operating load current is roughly half of the I LIMIT(NOM). Equation 7 shows the rule of thumb.I V R OPMAX CB NOM DSON NOM =()()•()27Note that the R DSON(NOM) is at the LTC4213 nominal operating ∆V GSMAX rather than at typical vendor spec.Table 1 gives the nominal operating ∆V GSMAX at the various operating V CC . From this table users can refer to the MOSFET’s data sheet to obtain the R DSON(NOM) value.Table 1. Nominal Operating ∆V GSMAX for Typical Bias Supply VoltageV CC (V)∆V GSMAX (V)2.3 4.32.5 5.02.7 5.63.0 6.53.37.05.07.06.07.0Load Supply Power-Up after Circuit Breaker Armed Figure 4 shows a normal power-up sequence for the circuit in Figure 1 where the V IN load supply power-up after circuit breaker is armed. V CC is first powered up by an auxiliary bias supply. V CC rises above 2.07V at time point 1. V ON exceeds 0.8V at time point 2. After a 60µs debounce delay, the GATE pin starts ramping up at time point 3. The external MOSFET starts conducting at time point 4. At time point 5, V GATE exceed ∆V GSARM and the circuit breaker is armed. After 50µs (t READY delay), READY pulls high by an external resistor at time point 6. READY signals the V IN load supply module to start its ramp. The load supply begins soft-start ramp at time point 7. The load supply ramp rate must be slow to prevent circuit breaker tripping as in equation (8).∆∆V t I I C IN OPMAX LOADLOAD<−()8Where I OPMAX is the maximum operating current defined by equation 7.For illustration, V CB = 25mV and R DSON = 3.5m Ω at the nominal operating ∆V GSMAX . The maximum operating current is 3.5A (refer to equation 7). Assuming the load can draw a current of 2A at power-up, there is a margin of 1.5A available for C LOAD of 100µF and V IN ramp rate should be <15V/ms. At time point 8, the current through the MOSFET reduces after C LOAD is fully charged.APPLICATIO S I FOR ATIOW UUU1516174213fThe selected MOSFET V GS absolute maximum rating should meet the LTC4213 maximum ∆V GSMAX of 8V.Other MOSFET criteria such as V BDSS , I DMAX , and R DSON should be reviewed. Spikes and ringing above maximum operating voltage should be considered when choosing V BDSS . I DMAX should be greater than the current limit. The maximum operating load current is determined by the R DSON value. See the section on “Calculating Current Limit” for details.Supply RequirementsThe LTC4213 can be powered from a single supply or dual supply system. The load supply is connected to the SENSEP pin and the drain of the external MOSFET. In the single supply case, the V CC pin is connected to the load supply, preferably with an RC filter. With dual supplies,V CC is connected to an auxiliary bias supply V AUX where V AUX voltage should be greater or equal to the load supply voltage. The load supply voltage must be capable of sourcing more current than the circuit breaker limit. If the load supply current limit is below the circuit breaker trip current, the LTC4213 may not react when the output overloads. Furthermore, output overloads may trigger UVLO if the load supply has foldback current limit in a single supply system.V IN Transient and Overvoltage ProtectionInput transient spikes are commonly observed whenever the LTC4213 responds to overload. These spikes can be large in amplitude, especially given that large decoupling capacitors are absent in hot swap environments. These short spikes can be clipped with a transient suppressor of adequate voltage and power rating. In addition, the LTC4213can detect a prolonged overvoltage condition. WhenAPPLICATIO S I FOR ATIOW UUU point 6 should be within the circuit breaker limits. Other-wise, the system fails to start and the circuit breaker trips immediately after arming. In most applications additional external gate capacitance is not required unless C LOAD is large and startup becomes problematic. If an external gate capacitor is employed, its capacitance value should not be excessive unless it is used with a series resistor. This is because a big gate capacitor without resistor slows down the GATE turn off during a fault. An alternative method would be a stepped I SEL pin to allow a higher current limit during startup.In the event of output short circuit or a severe overload, the load supply can collapse during GATE ramp up due to load supply current limit. The chosen MOSFET must withstand this possible brief short circuit condition before time point 6 where the circuit breaker is allowed to trip. Bench short circuit evaluation is a practical verification of a reliable design. To have current limit while powering a MOSFET into short circuit conditions, it is preferred that the load supply sequences to turn on after the circuit breaker is armed as described in an earlier section.Power-Off CycleThe system can be powered off by toggling the ON pin low.When ON is brought below 0.76V for 5µs, the GATE and READY pins are pulled low. The system resets when ON is brought below 0.4V for 80µs.MOSFET SelectionThe LTC4213 is designed to be used with logic (5V) and sub-logic (3V) MOSFETs for V CC potentials above 2.97V with ∆V GSMAX exceeding 4.5V. For a V CC supply range between 2.3V and 2.97V, sub-logic MOSFETs should be used as the minimum ∆V GSMAX is less than 4.5V.1819Information furnished by Linear Technology Corporation is believed to be accurate and reliable.However, no responsibility is assumed for its use.

采用面向低噪声的运放进行设计
采用面向低噪声的运放进行设计物理过程的现实使我们无法获得具有完美精度、零噪声、无穷大开环增益、转换速率和增益带宽乘积的理想运放。
但是，我们期待一代又一代连续面市的放大器可比前一代的放大器更好。
那么，低1/f 噪声运放的下一步会怎么样呢?回到1985 年，ADI的George Erdi 设计了LT1028。
30 多年过去了，该器件依然是市面上低频条件下电压噪声最低的运放，其在1kHz 时的输入电压噪声密度为0.85nV/√Hz，在0.1Hz 至10Hz 时的输入电压噪声为35nVP-P。
直到今年，一款新型放大器LT6018 才对LT1028 的地位提出了挑战。
LT6018 的0.1Hz 至10Hz 输入电压噪声为30nVP-P，并具有一个1Hz 的1/f 拐角频率，但是其宽带噪声为1.2nV/√Hz。
结果是，LT6018 是适合较低频率应用的较低噪声选择，而LT1028 则可为很多宽带应用提供更好的性能，如图 1 所示。
图1：LT1028 和LT6018 积分电压噪声嘈杂的噪声令人苦恼但是，与针对某个给定频段选择具最低电压噪声密度(en) 的放大器相比，设计低噪声电路要复杂得多。
如图 2 所示，其他噪声源开始起作用，不相干噪声源以平方根之和组合起来。
图2：运放电路噪声源首先，把电阻器看作是噪声源。
电阻器天生具有与电阻值的平方根成比例的噪声。
在300K 的温度下，任何电阻器的电压噪声密度为en = 0.13√R nV/√Hz。
该噪声也可被视为一种诺顿(Norton) 等效电流噪声：in = en/R = 0.13/√R nA/√Hz。
因此，电阻器具有一个17 zeptoWatts 的噪声功率。
优良的运放将具有低于该值的噪声功率。
例如：LT6018 的噪声功率(在1kHz 频率下测量) 约为1 zeptoWatt。
在图2 的运放电路中，源电阻、增益电阻器和反馈电阻器(分别为RS、R1 和R2) 均为产生电路噪声的因素。
