Dual and Quad Micropower Single Supply
Rail-to-Rail Input and Output (RRIO) Op Amp
ISL28278, ISL28478
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 4A in the disabled state.
