Single, Dual, and Quad Micropower, Low Drift, RRIO

Operational Amplifiers

ISL28130, ISL28230, ISL28430

Features

The ISL28130, ISL28230 and ISL28430 are single, dual and

quad micropower, low offset drift operational amplifiers that are

optimized for single and dual supply operation from 1.8V to 5.5V

and ±0.9V to ±2.75V. Their low supply current of 20µA and

rail-to-rail input/output enable the ISL28130, ISL28230, and

ISL28430 to be an excellent general-purpose op amp for a range

of applications. The ISL28130, ISL28230 and ISL28430 are

ideal for handheld devices that operate off 2 AA or single Li-ion

batteries.
