Dual and Quad Micropower Single Supply
Rail-to-Rail Input and Output (RRIO)
Precision Op Amp
The ISL28286 and ISL28486 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 EL8186.
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 ISL28286 and ISL28486 draw minimal supply current
while meeting excellent DC-accuracy, AC-performance,
noise and output drive specifications. The ISL28286
contains a power down enable pin that reduces the power
supply current to less than 4µA max in the disabled state.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations.
Intersil Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
