Dual and Quad Micropower Single Supply

Rail-to-Rail Input and Output (RRIO)

Precision Op Amp

The ISL28286 and ISL28486 are dual and quad channel

micropower operational amplifiers optimized for single

supply operation over the 2.4V to 5V range. They can be

operated from one lithium cell or two Ni-Cd batteries. For

equivalent performance in a single channel op amp

reference EL8186.

These devices feature an Input Range Enhancement Circuit

(IREC) which enables them to maintain CMRR performance

for input voltages 10% above the positive supply rail and

down to the negative supply. The output operation is rail to

rail.

The ISL28286 and ISL28486 draw minimal supply current

while meeting excellent DC-accuracy, AC-performance,

noise and output drive specifications. The ISL28286

contains a power down enable pin that reduces the power

supply current to less than 4µA max in the disabled state.

*Add “-T7” suffix for tape and reel. Please refer to TB347 for details

on reel specifications.

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.
