Dual Micropower Single Supply
Rail-to-Rail Input and Output (RRIO)
Precision Op-Amp
The ISL28286 and ISL28486 are Dual and Quad channel
micropower precision operational amplifiers optimized for
single supply operation at 5V down to 2.4V. For equivalent
performance in a single channel op-amp reference EL8186.
The ISL28286 and ISL28486 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 10% above the positive supply rail and
to ground with only a slight degradation of the CMRR
performance. The output operation is rail to rail.
Both parts draw minimal supply current while meeting
excellent DC-accuracy, AC-performance, noise and output
drive specifications.
The ISL28286 and ISL28486 can be operated from a single
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.
