These devices require only 900µA peramplifier, and operate from either a single supply ( 2.7Vto 6.5V) or dual supplies ( 1.35V to 3.25V) with acommon-mode voltage range that extends 250mVbeyond VEE and VCC. They are capable of driving 250Ωloads and are unity-gain stable. In addition, theMAX4131/ MAX4133 feature a shutdown mode in whichthe outputs are placed in a high-impedance state andthe supply current is reduced to only 25µA per amplifier.With their rail-to-rail input common-mode range andoutput swing, the MAX4130–MAX4134 are ideal for lowvoltage, single-supply operation. Although the minimumoperating voltage is specified at 2.7V, the devicestypically operate down to 1.8V. In addition, low offsetvoltage and high speed make them the ideal signalconditioning stages for precision, low-voltage dataacquisition systems. The MAX4130 is offered in thespace-saving 5-pin SOT23 package. The MAX4131 isoffered in the ultra-small 6-bump, 1mm x 1.5mm chipscale package (UCSP ).

MAX4130–MAX4134Single/Dual/Quad, Wide-Bandwidth, Low-Power,Single-Supply, Rail-to-Rail I/O Op AmpsApplications InformationRail-to-Rail Input StageDevices in the MAX4130–MAX4134 family of highspeed amplifiers have rail-to-rail input and outputstages designed for low-voltage, single-supply operation. The input stage consists of separate NPN andPNP differential stages that combine to provide aninput common-mode range that extends 0.2V beyondthe supply rails. The PNP stage is active for input voltages close to the negative rail, and the NPN stage isactive for input voltages near the positive rail. The inputoffset voltage is typically below 200µV. The switchovertransition region, which occurs near VCC / 2, has beenextended to minimize the slight degradation in common-mode rejection ratio caused by the mismatch ofthe input pairs. Their low offset voltage, high bandwidth, and rail-to-rail common-mode range make theseop amps excellent choices for precision, low-voltagedata-acquisition systems.Since the input stage switches between the NPN andPNP pairs, the input bias current changes polarity asthe input voltage passes through the transition region.Reduce the offset error caused by input bias currentsflowing through external source impedances by matching the effective impedance seen by each input(Figures 1a, 1b). High source impedances, togetherwith input capacitance, can create a parasitic pole thatproduces an underdamped signal response. Reducingthe input impedance or placing a small (2pF to 10pF)capacitor across the feedback resistor improvesresponse.The MAX4130–MAX4134s’ inputs are protected fromlarge differential input voltages by 1kΩ series resistorsand back-to-back triple diodes across the inputs(Figure 2). For differential input voltages less than 1.8V,input resistance is typically 500kΩ. For differential inputvoltages greater than 1.8V, input resistance is approximately 2kΩ. The input bias current is given by the following equation:IBIAS VDIFF - 1.8V2kΩ1kΩ1kΩFigure 2. Input Protection Circuit10
Single/Dual/Quad, Wide-Bandwidth, Low-Power,Single-Supply, Rail-to-Rail I/O Op AmpsDriving a capacitive load can cause instability in mosthigh-speed op amps, especially those with low quiescent current. The MAX4130–MAX4134 have a high tolerance for capacitive loads. They are stable withcapacitive loads up to 160pF. Figure 4 gives the stableoperating region for capacitive loads. Figures 5 and 6show the response with capacitive loads and theresults of adding an isolation resistor in series with theoutput (Figure 7). The resistor improves the circuit’sphase margin by isolating the load capacitor from theop amp’s output.500450LOAD CAPACITANCE (pF)VOLTAGE (1V/div)VCC 3V, RL 10kΩ to LEOPERATINGREGION100OUTRL TO VEEVOUT VCC/2500TIME (1µs/div)0.1110100LOAD RESISTANCE (kΩ)Figure 4.

Figure 3 shows the inputvoltage range and output voltage swing of a MAX4131connected as a voltage follower. With a 3V supplyand the load tied to ground, the output swings from0.00V to 2.90V. The maximum output voltage swingdepends on the load, but will be within 150mV of a 3Vsupply, even with the maximum load (500Ω to ground).
Power-Up and Shutdown ModeThe MAX4130–MAX4134 amplifiers typically settle within 1µs after power-up. Figures 9 and 10 show the output voltage and supply current on power-up, using thetest circuit of Figure 8.The MAX4131 and MAX4133 have a shutdown option.When the shutdown pin (SHDN) is pulled low, the supply current drops below 25µA per amplifier and theamplifiers are disable
In addition, low offset voltage and high speed make them the ideal signal-conditioning stages for precision, low-voltage data-acquisition systems. The MAX4130 is offered in the space-saving 5-pin SOT23 package. The MAX4131 is . Single/Dual/Quad, Wide-Bandwidth, Low-Po

Bandwidth Learning Objectives: At the end of this topic you should be able to: recall that the bandwidth is the frequency range over which the voltage gain is greater than 1 2 (70%) of its maximum value; estimate this bandwidth from a frequency response curve; use the gain-bandwidth product (unity-gain bandwidth) to estimate bandwidth.
