34µA 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.

special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate PLUS ANNEAL - e3 termination
finish, which is 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.

... Applications Information Introduction The ISL28168 is a single CMOS rail-to-rail input, output (RRIO) operational amplifier with an enable feature. The ISL28268 is a dual version without the enable feature. Both devices are designed to operate from single supply (2.4V to 5.5V) or dual supplies (±1.2V to ±2.75V). ...

... In the disabled state (output in a high impedance state), the part consumes typically 10µA at room temperature. By disabling the part, multiple ISL28168 parts can be connected together as a MUX. In this configuration, the outputs are tied together in parallel and a channel can be selected by the EN pin. The loading effects ...
