39µA Micropower Single and Dual
Precision Rail-to-Rail Input-Output (RRIO)
Low Input Bias Current Op Amps
The ISL28156 and ISL28256 are micropower precision
operational amplifiers optimized for single supply operation
at 5V and can operated down to 2.4V.
These devices feature an Input Range Enhancement Circuit
(IREC) which enables them to maintain CMRR performance
for input voltages greater than the positive supply. The input
signal is capable of swinging 0.5V above a 5.0V supply (0.25
for a 2.5V supply) and to within 10mV from ground. The
output operation is rail-to-rail.
The 1/f corner of the voltage noise spectrum is at 1kHz. This
results in low frequency noise performance which can only
be found on devices with an order of magnitude higher
supply current.
ISL28156 and ISL28256 can be operated from one lithium
cell or two Ni-Cd batteries. The input range includes both
positive and negative rail. The output swings to both rails.

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.
