AD7713 is a 24-bit low-power battery-powered signal conditioning ADC that uses CMOS technology. It has 3 channels of programmable gain front end, gain range from 1 to 128. AD7713 also has low-pass filter, read/write calibration coefficients, microcontroller serial interface and other functions.
The AD7713 is a charge‑balancing, 24‑bit ADC designed for loop‑powered transmitters, RTD transducers, process control, and portable industrial instruments. It integrates a programmable‑gain front end, on‑chip digital filter, and bidirectional serial interface for microcontroller‑based systems.
Key features include two differential analog inputs, one single‑ended high‑voltage input, low‑power operation (typical 3.5 mW standby), self‑calibration, and a wide supply range (5 V to 10 V). The device offers programmable filter cutoffs, on‑chip current sources for RTD excitation, and extensive calibration options.
