Single, Dual and Quad Micropower Single

Supply Rail-to-Rail Input and Output

(RRIO) Precision Op Amp

The ISL28176, ISL28276 and ISL28476 are single, 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.

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 ISL28276 and ISL28476 draw minimal supply current

while meeting excellent DC-accuracy, AC-performance,

noise and output drive specifications. The ISL28276 (QSOP

package only) contains a power-down enable pin that

reduces the power supply current to typically 4µA in the

disabled state.

NOTE: These Intersil Pb-free plastic packaged products employ

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.
