DATASHEET
ISL28130, ISL28230, ISL28430
Single, Dual, and Quad Micropower, Low Drift, RRIO Operational Amplifiers
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.
