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 2AA or single

Li-ion batteries.

The ISL28130 is available in industry standard pinouts for 5 Ld

SOT-23, 5 Ld SC70 and 8 Ld SOIC packages. The ISL28230 is

available in industry standard pinouts for 8 Ld MSOP, 8 Ld

SOIC and 8 Ld DFN packages. The ISL28430 is available in

14 Ld TSSOP and 14 Ld SOIC packages. Commercial devices

operate over the temperature range of 0°C to 70°C. Full

temperature range devices operate over the temperature

range of -40°C to 125°C.
