AD7710 is a 24-bit, fully differential analog front end with 2-channel programmable gain, low power consumption (25mW typical), and support for external reference and single/dual power supply. Applications include weighing scales, temperature sensors, process control, smart sensors, chromatography, etc.
The AD7710 is a signal‑conditioning analog‑to‑digital converter designed for weigh‑scale, thermocouple, process‑control, smart‑transmitter and chromatography applications. It integrates a programmable‑gain front end, on‑chip digital filter, and a bidirectional serial interface for microcontroller control.
Key features include two differential input channels, selectable gains from 1 to 128, internal/external reference options, low‑power consumption (25 mW typical), and a 2.5 V reference output. The device is offered in 24‑lead DIP and SOIC packages and supports both single‑ and dual‑supply operation.
