HI7191 24-Bit, High Precision, Sigma Delta A/D Converter 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.
The on-demand converter auto-calibrate function is capable of removing offset an
