General Description
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 0.1A, 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. These features make the
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, MAX, and SO packages. For
greater accuracy, the A grade MAX and SO packages
are tested to guarantee 20V (max) offset voltage at
+25°C and less then 2V/°C drift.
