_______________general description the max402/max403/max438/max439 micropower op amps combine high-speed performance with low-power operation. the max402/max403 are compensated for unity-gain stability, while the max438/max439 are com- pensated for stability in applications with a closed-loop gain (a vcl ) of 5v/v or greater. the max402/max438 require less than 75? of supply current while delivering 2mhz bandwidth with 6v/? slew rate (max402), and 6mhz gain bandwidth with 10v/? slew rate (max438). for applications requiring increased speed, the max403/max439 consume less than 375? of supply current while delivering 10mhz gain bandwidth with 40v/? slew rate (max403), and 25mhz gain bandwidth with 48v/? slew rate (max439). ________________________applications low-power signal processing filters portable instruments remote sensors ____________________________features max402 ? 2mhz unity-gain bandwidth ? 6v/? slew rate ? 75? max supply current max403 ? 10mhz unity-gain bandwidth ? 40v/? slew rate ? 375? max supply current max438 ? 6mhz gain bandwidth (a vcl 3 5v/v) ? 10v/? slew rate ? 75? max supply current max439 ? 25mhz gain bandwidth (a vcl 3 5v/v) ? 48v/? slew rate ? 375? max supply current ______________ordering information ordering information continued at end of data sheet. * dice are specified at t a = +25?, dc parameters only. max402/max403/max438/max439 high-speed, low-voltage, micropower op amps ________________________________________________________________ maxim integrated products 1 n.c. v+ out null v- in+ in- null top view dip/so 1 2 3 4 8 7 6 5 max402 max403 max438 max439 __________________pin configuration max402 max403 20k 20k 1n914 1n914 half-wave rectifier ________typical application circuit call toll free 1-800-998-8800 for free samples or literature. 19-3786; rev 2; 10/94 part max402 cpa max402csa max402c/d 0? to +70? 0? to +70? 0? to +70? temp. range pin-package 8 plastic dip 8 so dice* max402epa max402esa -40? to +85? -40? to +85? 8 plastic dip 8 so

__________applications information input offset-voltage adjustment the null pins (1 and 5) can be used to null the input offset voltage. to adjust the amplifier? offset voltage, connect a potentiometer between the two null pins with the wiper connected to v-, as shown in figure 1. use a 10k potentiometer with the max402/max438, and a 2k potentiometer with the max403/max439. offset voltage can be adjusted over a range of approxi- mately 12mv with these trim potentiometers. operating supply voltage the max402/max403/max438/max439 are specified with ?v power supplies, but also operate with dual supplies down to ?v or single supplies ranging from +6v to +10v if the common-mode input voltage is kept between (v- + 1.5v) and (v+ - 1.5v). with a single +6v supply, the common-mode input voltage ranges between +1.5v and +4.5v. layout and bypassing bypass the power-supply inputs with 0.1? ceramic capacitors positioned as close to the power-supply pins as possible. to maximize performance in high-speed applications, use a ground plane. connections to the amplifier? input terminals should be as short and direct as possible with a minimum of inductance and capaci- tance. stray capacitance at the input terminals adds to the amplifier? approximate 3pf input capacitance, and can limit overall bandwidth. also, minimize lead lengths in connections from the power-supply bypass capacitors to ground to further reduce inductance. surface-mount (chip) capacitors are ideal for this application. slew rate vs. input voltage like most high-speed op amps, the slew rate of the max402/max403/max438/max439 depends on the signal level driving the amplifier inputs. slew-rate limit- ing in high-speed circuits becomes more significant as the amplifier? closed-loop gain increases (inadequate gain bandwidth is more likely to limit performance in low-gain circuits). for this reason, the max438/ max439 have been characterized for slew rate vs. input voltage, as shown in the max438/max439 slew rate vs. input voltage graph in the typical operating characteristics. overload conditions the amplifier inputs withstand differential voltages equal to the power-supply rails without requiring external clamp diodes or input current-limiting resistors. schottky diodes, used internally throughout the devices, prevent saturation of the internal transistors and allow the ampli- fiers to recover quickly from overload conditions. many op amps exhibit phase reversal at the output when the input common-mode voltage range is exceeded? potentially serious problem in servo-con- trol systems. phase reversal protection circuitry in the max402/max403/max438/max439 eliminates this problem for any input voltage level. each amplifier? output stage employs a current-limit circuit that prevents amplifier damage in the event of a fault condition. the output may be shorted to either power supply or ground continuously without damage. max402/max403/max438/max439 high-speed, low-voltage, micropower op amps 10 ______________________________________________________________________________________ _____________________pin description amplifier signal output out 6 positive power supply (v cc ) v+ 7 no connect?o internal connection n.c. 8 negative power supply (v ee ) v- 4 noninverting input in+ 3 pin inverting input in- 2 offset-voltage adjustment null 1, 5 function name max402 max403 max438 max439 2 3 1 r v- v+ 6 7 4 5 0.1 m f r = 10k w max402/438 r = 2k w max403/439 0.1 m f figure 1. offset-voltage adjustment
