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 ±0.825V to ±3.0V. Their low supply current of 18µA 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.

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.
