39µA Micropower Single and Dual
Rail-to-Rail Input-Output Low Input Bias
Current (RRIO) Op Amps
The ISL28166 and ISL28266 are micropower precision
operational amplifiers optimized for single supply operation
at 5V and can operate 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.
ISL28166 and ISL28266 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.
