Product Status: Mass Production
OVERVIEW
The ISL28233 and ISL28433 are dual and quad micropower, chopper stabilized operational amplifiers that are optimized for single and dual supply operation from 1.65V 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.
