Overview
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 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 specs.
The HI7191 contains a serial I/O port and is compatible with most synchronous transfer formats including both the Motorola 6805/11 series SPI and Intel 8051 series SSR protocols.
A sophisticated set of commands gives the user control over calibration, PGIA gain, device selection, standby mode, and several other features.
The On-chip Calibration Registers allow the user to read and write calibration data.
