AD7783 is a single-channel, 24-bit A/D converter with ±2.56 V or ±160 mV input ranges, ISOURCE Select™ current source and fixed frequency sampling, designed for sensor measurement, industrial process control, temperature measurement, pressure measurement, weighing scales and portable instrumentation applications.
The AD7783 is a single‑channel, 24‑bit sigma‑delta ADC with pin‑configurable input ranges of +160 mV or +2.56 V and integrated 200 µA excitation current sources. It operates in master or slave mode over a 3 V or 5 V supply and provides a fixed 19.79 Hz update rate with simultaneous 50 Hz and 60 Hz line‑frequency rejection.
The document includes functional block diagrams, pin descriptions, timing characteristics, absolute maximum ratings, ordering information, noise performance data, and detailed descriptions of the digital interface and operating modes. It is intended for designers integrating the AD7783 into measurement, instrumentation, and industrial control applications.
