The AD7710 is a 24-bit, no missing codes, charge balancing ADC with 2-channel programmable gain front end and low-pass filter. It can be widely used in weighing scales, thermocouples, process control, smart transmitters, and chromatography applications.
The AD7710 is a complete analog front‑end for low‑frequency measurement applications. It accepts low‑level signals directly from strain gauges or transducers and provides a 24‑bit sigma‑delta conversion with no missing codes. The device includes a programmable gain front‑end, on‑chip digital filter, and a bidirectional serial interface that can be controlled by a microcontroller.
Typical applications include weigh scales, thermocouples, process control, smart transmitters, and chromatography. The ADC offers low power consumption (25 mW typical, 7 mW in standby), selectable supply voltages (5 V to 10 V), and extensive calibration options for high accuracy.
