General Description
The MAX4194 is a variable-gain precision instrumenta-
tion amplifier that combines Rail-to-Rail single-supply
operation, outstanding precision specifications, and a
high gain bandwidth. This amplifier is also offered in
three fixed-gain versions: the MAX4195 (G = +1V/V), the
MAX4196 (G = +10V/V), and the MAX4197 (G =
+100V/V). The fixed-gain instrumentation amplifiers fea-
ture a shutdown function that reduces the quiescent
current to 8A. A traditional three operational amplifier
configuration is used to achieve maximum DC precision.
The MAX4194–MAX4197 have rail-to-rail outputs and
inputs that can swing to 200mV below the negative rail
and to within 1.1V of the positive rail. All parts draw only
93A and operate from a single +2.7V to +7.5V supply
or from dual ±1.35V to ±3.75V supplies. These amplifiers
are offered in 8-pin SO packages and are specified for
the extended temperature range (-40°C to +85°C).
See the MAX4198/MAX4199 data sheet for single-supply,
precision differential amplifiers.
