HI7190IB - Sigma Delta A/D Converter
HI7190 24-Bit, High Precision, Sigma Delta A/D Converter The Intersil 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.
The on-demand converter autocalibrate function is capable of removing offset and
