Overview

The ISL28191EVAL1Z is designed to enable the IC to operate from a single supply (+3VDC to +5.5VDC) or from split supplies (±1.5VDC to ±2.75VDC). The board is configured for a single op amp connected for differential input with a closed loop gain of 10. A single external reference voltage (VREF) pin is provided, as well as a user-selectable voltage divider (filter included).

The ISL28191 amplifiers feature ultra-low noise, ultra-low distortion, and rail-to-rail output drive capability. They are designed to operate with single and dual supplies from +5.5VDC (±2.75VDC) down to +3VDC (±1.5VDC).
