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.
