General Description

The Harris HI7190 is a monolithic instrumentation, sigma delta A/D converter which operates from ±5V supplies.

Both the signal and reference inputs are fully differential for maximum flexibility and performance.

An internal Programmable Gain Instrumentation Amplifier (PGIA) provides input gains from 1 to 128 eliminating the need for external pre-amplifiers.
