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.
