This document describes the features and characteristics of Analog Devices' AD7712* LC2MOS Signal Conditioning ADC. The product features a 24-bit charge-balancing ADC, high and low level analog input channels, programmable gain, and the ability to read/write calibration coefficients, among other features.
The AD7712 is a 24‑bit charge‑balancing sigma‑delta ADC with programmable gain (1‑128) and dual analog input channels. It offers high accuracy (+0.0015% non‑linearity) and low power consumption, making it suitable for smart transmitters, process‑control instruments and portable industrial devices.
The handbook details functional block diagrams, pin configurations, timing characteristics, power‑supply requirements, calibration procedures and full technical specifications. Ordering information and package options (PDIP, SOIC) are also included.
