Dual Precision Micropower Single Supply

Rail-to-Rail Input and Output Precision

Op-Amps

The ISL28276 is a dual 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 features an Input Range Enhancement Circuit

(IREC) which enables the ISL28276 to maintain CMRR

performance for input voltages greater than the positive

supply. 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 ISL28276 draws 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 can be operated from one lithium cell or two

Ni-Cd batteries. The input range includes both positive and

negative rail.

Ordering Information

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.
