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