Dual and Quad Precision Micropower
Single Supply Rail-to-Rail Input and
Output Precision Op Amps
The ISL28276 and ISL28476 are Dual and Quad channel
micropower precision operational amplifier optimized for
single supply operation at 5V and can operate down to 2.4V.
For equivalent performance in a single channel op-amp
reference EL8176.
The ISL28276 and ISL28476 feature an Input Range
Enhancement Circuit (IREC) which enables both parts to
maintain CMRR performance for input voltages equal to the
positive and negative supply rails. The input signal is
capable of swinging 0.5V above a 5.0V supply (0.25V for a
2.4V supply) and to within 10mV from ground. The output
operation is rail to rail.
The both parts draw minimal supply current while meeting
excellent DC-accuracy, AC-performance, noise and output
drive specifications. Offset current, voltage and current
noise, slew rate, and gain-bandwidth product are all two to
ten times better than other micropower op-amps with
equivalent supply current ratings.
The ISL28276 and ISL28476 can be operated from one
lithium cell or two Ni-Cd batteries. The input range includes
both positive and negative rail.

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.
