This document is the instruction manual for CS5509, which introduces the features and characteristics of the product.
The CS5509 is a single‑supply, 16‑bit delta‑sigma analog‑to‑digital converter offering up to 200 samples per second. It features on‑chip self‑calibration, high common‑mode rejection, and selectable unipolar or bipolar input ranges, making it suitable for loop‑powered transmitters, panel meters, weigh scales, and battery‑powered instruments.
The device operates from a 3.3 V or 5 V supply, consumes as little as 1.7 mW, and provides a variety of digital interfaces. Detailed electrical characteristics, timing diagrams, and environmental handling information are included for designers.
