Micropower Op-Amps extend battery life in portable devices.October 22, 2010 -
ISL28233 and ISL28433 are dual and quad micropower, chopper stabilized op-amps optimized for single and dual supply operation from 1.65-6.0 V and ±0.825 to ±3.0 V. Quiescent current draw of 18 µA suits handheld devices that operate off 2 AA or single Li-ion batteries. Featuring rail-to-rail inputs and output, products operate over -40 to +125°C range and offer 6 µV max input offset voltage, 0.05 µV/°C max offset drift, and 1.0 µVP-P typ noise from 0.01-10 Hz.
