Overview

The ISL28233 is a dual micropower, chopper stabilized operational amplifier that is optimized for single and dual supply operation from 1.65V to 6.0V and ±0.825V to ±3.0V. Its low supply current of 18µA and wide input range enable the ISL28233 to be an excellent general purpose op amp for a wide range of applications. This op amp is 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 and operates over the temperature range of -40 °C to +125 °C.
