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 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. Both Amplifiers have PMOS inputs that provide less than 30pA input bias currents.
The Amplifiers CAN be operated from one lithium cell or two Ni-Cd batteries. The Amplifiers input range goes from below ground to slightly above positive rail. The output stage swings completely to ground or positive supply; no pull-up or pull-down resistors are needed.
