HI7191 Sigma Delta A/D Converter

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.
