HI7190EVAL规格书详情
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 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 resolution and conversion speed over a wide dynamic range. The HI7190 and HI7191 are functionally the same device, but the HI7190 has tighter linearity specifications.
