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 consists 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. The feedback terminals allow zero input to be translated to any output offset, including ground. A feedback divider controls the overall gain of the amplifier. The additional precision amplifier can be used to generate higher gain, with smaller feedback resistors or used to generate a reference voltage. The instrumentation amp (Amp A) is compensated for a gain of 100 or more and the precision amp (Amp B) is unity gain stable.
