Description
The ISL28133 is a single micropower, chopper stabilized operational amplifier that is optimized for single supply operation from 1.8V to 5.5V. Its low supply current of 18µA and wide input range enable the ISL28133 to be an excellent general purpose op amp for a range of applications. The ISL28133 is ideal for handheld devices that operate off 2AA or single Li-ion batteries. The ISL28133 is available in the 5 Ld SOT-23, the 5 Ld SC70 and the 6 Ld 1. 6mmx1. 6mm µTDFN packages. All devices operate over the extended temperature range of -40°C to +125°C.
