Micropower, Single-supply, Rail-to-rail, Precision Instrumentation Amplifiers Integrated Products

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 preci- sion. The MAX4194MAX4197 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 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 (-40C to +85C).
