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 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 wide 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 and 8Ld SOIC packages. The ISL28430 is
available in 14 Ld TSSOP and 14 Ld SOIC packages. All
devices operate over the temperature range of 0°C to
+70°C.
