ISL28130_1012 Datasheet, PDF (1/19 Pages) Intersil Corporation – Single, Dual, and Quad Micropower, Low Drift, RRIO Operational Amplifiers

Single, Dual, and Quad Micropower, Low Drift, RRIO
Operational Amplifiers
ISL28130, ISL28230, ISL28430
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 1.65V to
5.5V and ±0.825V to ±2.75V. Their low supply current of 20µA
and rail-to-rail input range enable the ISL28130, ISL28230,
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.
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, 8Ld SOIC
and 8 Ld DFN packages. The ISL28430 is available in 14 Ld
TSSOP and 14 Ld SOIC packages. All devices operate over the
temperature range of -40°C to +125°C.
