ISL28233, ISL28433 FN7692
Rev 3.00
July 26, 2011 Dual and Quad Micropower Chopper Stabilized, RRIO Operational Amplifiers
The ISL28233 and ISL28433 are dual and quad micropower,
chopper stabilized operational amplifiers that are optimized
for single and dual supply operation from 1.8V to 6.0V and
В±0.825V to В±3.0V. Their low supply current of 18ВµA and wide
input range enable the ISL28233, ISL28433 to be excellent
general purpose op amps for a wide range of applications. The
ISL28233 and ISL28433 are ideal for handheld devices that
operate off 2 AA or single Li-ion batteries. Features The ISL28233 is available in 8 Ld MSOP, 8 Ld SOIC and 8 Ld
DFN packages. The ISL28433 is available in 14 Ld TSSOP,
14 Ld SOIC and 14 Ld 3mmx4mm TDFN packages. All devices
operate over the temperature range of -40°C to +125°C. Low Noise (0.01Hz to 10Hz) . 1.0µVP-P, Typ. Related Literature Operating Temperature Range -40°C to +125°C See AN1596, “ISL28233SOICEVAL1Z Evaluation Board
