Micropower, Single-Supply, Rail-to-Rail, Precision Instrumentation Amplifiers
General Description
The MAX4194 is a variable-gain precision instrumentation 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 feature a shutdown function that reduces the quiescent current to 8µA. 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 within 200mV of the negative rail and to within 1.
