HI7191 Datasheet Sigma Delta A/D Converter

Manufacturer: Intersil (now Renesas)

Datasheet Details

The Intersil HI7191 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.
