ISL28138, ISL28238
4.5MHz, Single and Dual Precision Rail-to-
Rail Input-Output (RRIO) Op Amps with
Very Low Input Bias Current
The ISL28138 and ISL28238 are 4.5MHz low-power single
and dual operational amplifiers. The parts are optimized for
single supply operation from 2.4V to 5.5V, allowing operation
from one lithium cell or two Ni-Cd batteries.
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 parts draw minimal supply current (900μA per amplifier)
while meeting excellent DC accuracy, AC performance,
noise and output drive specifications. The ISL28138 features
an enable pin that can be used to turn the device off and
reduce the supply current to less than 20μA. Operation is
guaranteed over -40°C to +125°C temperature range
Features

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.
