Micropower / Single-Supply / Rail-to-Rail / Precision Instrumentation Amplifiers
General DescriptionThe 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 8µA. A traditional three operational amplifier
configuration is used to achieve maximum DC preci-
sion.
The MAX4194–MAX4197 have rail-to-rail outputs and
inputs that can swing to within 200mV of the negative rail
and to within 1.1V of the positive rail. All parts draw only
93µA 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-sup-
ply, precision differential amplifiers.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1:Guaranteed by design.
Note 2:Maximum output current (sinking/sourcing) in which the gain changes by less than 0.1%.
Note 3:This specification represents the typical temperature coefficient of an on-chip thin film resistor. In practice, the temperature
coefficient of the gain for the MAX4194 will be dominated by the temperature coefficient of the external gain-setting resistor.
