Micropower, Single Supply, Rail-to-Rail Input-Output Instrumentation Amplifier and Precision Operational Amplifier

The ISL28274 is a combination of a micropower instrumentation amplifier (Amp A) with a low power precision
amplifier (Amp B) in a single package. The ISL28474 consist of two micropower instrumentation amplifiers (Amp A) and two low power precision amplifiers (Amp B) in a single package. The amplifiers are optimized for operation at 2.4V to 5V single supplies. Inputs and outputs can operate rail-to rail. As with all instrumentation amplifiers, a pair of inputs provide a high common-mode rejection and are completely independent from a pair of feedback terminals.
