Analog Devices AD7796/AD7797 Datasheet
The AD7796 and AD7797 are low‑power, 16‑/24‑bit sigma‑delta ADCs designed for bridge‑sensor applications such as weigh scales, strain gauges, and industrial process control. Each part includes an on‑chip instrumentation amplifier with a fixed gain of 128, a temperature sensor for bridge compensation, and supports both internal and external clock sources.
The document details electrical specifications, timing characteristics, pin configurations, and recommended layouts. It also includes application notes, such as a weigh‑scale implementation, and an ordering guide for the 16‑lead TSSOP package options.
