HI7190 Datasheet | Intersil

Semiconductor 24-Bit, High Precision, Sigma Delta A/D Converter 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. The ondemand converter auto-calibrate function is capable of removing offset and gain errors existing in external and internal circuitry. The on-board user programmable digital filter provides over -120dB of 60/50Hz noise rejection and allows fine tuning of...
