Overview
Description
The ISL28634EV2Z board allows simple evaluation of the ISL28634 5V zero-drift programmable gain instrumentation amplifier. The board is designed with all the necessary components to easily connect the high-performance amplifier to an external signal. It can operate from a single supply of +2.5V to +5.5V or a dual supply of ±1.25V to ±2.75V.
