ISL28478EVAL1Z [INTERSIL]

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. These devices feature an Input Range Enhancement Circuit (IREC) that 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 typically to 4µA in the disabled state.
