The Analog Devices AD7793BRUZ is a low-power, low-noise 24-bit sigma-delta analog-to-digital converter with three differential inputs, an on-chip low-noise programmable-gain instrumentation amplifier and a precision band-gap reference, housed in a 16-lead TSSOP package. It operates from 2.7 V to 5.25 V and provides programmable output data rates from 4.17 Hz to 470 Hz. The device is intended for high-precision measurement of low-bandwidth signals in weighing, temperature and process-control systems.
