Overview

Description

Support is limited to customers who have already adopted these products.

The ISL28176, ISL28276 and ISL28476 are single, dual and quad channel micropower operational amplifiers optimized for single supply operation over the 2. 4V to 5V range. They can be operated from one lithium cell or two Ni-Cd batteries. These devices feature an Input Range Enhancement Circuit (IREC) which enables them to maintain CMRR performance for input voltages 10% above the positive supply rail and down to the negative supply. The output operation is rail-to-rail. The ISL28276 and ISL28476 draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. The ISL28276 (QSOP package only) contains a power-down enable pin that reduces the power supply current to typically 4µA in the disabled state.
