Overview

The ISL28133EVAL1Z evaluation board is configured as a precision high-gain (G = 10,000) differential amplifier and demonstrates the level of performance possible with this type of amplifier while operating from battery voltages as low as 2.4V.

The ISL28133 chopper-stabilized rail-to-rail op amp features a low 8µV maximum VOS over-temperature and a 0.1Hz 1/f noise corner frequency, enabling very high gain single-stage DC amplifiers that can operate from single cell batteries while consuming only 20µA of current.
