ISL28478

Description

The ISL28278 and ISL28478 are dual and quad channel micropower operational amplifiers optimized for single supply operation over the 2.4V to 5.5V range. They can be operated from one lithium cell or two Ni-Cd batteries. For equivalent performance in a single channel op amp reference EL8178. 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 to 100mV below the negative supply. The output operation is rail-to-rail. The ISL28278 and ISL28478 draw minimal supply current while meeting excellent DC-accuracy, AC-performance, noise and output drive specifications. The ISL28278 contains a power down enable pin that reduces the power supply current to typically 4A in the disabled state.
