The MAX4236/MAX4237 are high-precision op amps

that feature an exceptionally low offset voltage and off-

set voltage temperature coefficient without using any

chopper techniques. The MAX4236 and MAX4237 have

a typical large-signal, open-loop voltage gain of 120dB.

These devices have an ultra-low input-bias current of

1pA. The MAX4236 is unity-gain stable with a gain-

bandwidth product of 1.7MHz, while the MAX4237 is

stable for closed-loop gains greater than 5V/V with a

gain-bandwidth product of 7.5MHz. Both devices have

a shutdown function in which the quiescent current is

reduced to less than 0.1µA, and the amplifier output is

forced into a high-impedance state.

The input common-mode range of the MAX4236/

MAX4237 extends below the negative supply range, and

the output swings Rail-to-Rail

amplifiers ideal for applications with +3V or +5V single

power supplies. The MAX4236/MAX4237 are specified for

the extended temperature range (-40°C to +85°C) and

are available in tiny SOT23, µMAX, and SO packages. For

greater accuracy, the A grade µMAX and SO packages

are tested to guarantee 20µV (max) offset voltage at

+25°C and less then 2µV/°C drift.
