ISL28168, ISL28268
34A Micro-power Single and Dual
Rail-to-Rail Input-Output (RRIO) Low Input
Bias Current Op Amps
The ISL28168 and ISL28268 are micro-power operational
amplifiers optimized for single supply operation over a power
supply range of 2.4VDC to 5.5VDC. These devices draw
minimal supply current and operate rail-to-rail at the input
and output, while providing excellent DC-accuracy, noise
and output drive specifications. Competing devices seriously
degrade these parameters to achieve micro-power supply
current.
The parts 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 0.25V above the positive
supply and to 100mV below the negative supply with only a
slight degradation of the CMRR performance. The output
operation is rail-to-rail.
The 1/f corner of the voltage noise spectrum is at 100Hz.
This results in low frequency noise performance, which can
only be found on devices with an order of magnitude higher
supply current.
ISL28168 and ISL28268 can be operated from one lithium
cell or two Ni-Cd batteries. The ISL28168 contains an enable
pin feature that allows the device to be shutdown when not in
use.
