The AD7725 is a complete 16‑bit analog‑to‑digital converter with on‑chip, user‑programmable signal conditioning. It features a three‑stage FIR filter followed by a programmable post‑processor that can perform up to 130 million MAC operations per second. The device operates from a 5 V supply, supports both bipolar (±4 V) and unipolar (0‑4 V) input ranges, and is available in a 44‑lead MQFP package.
Key specifications include a 14.4 MHz maximum master clock, 108‑tap programmable filter, 33 mA typical power consumption, and an operating temperature range of –40 °C to +85 °C. The datasheet provides detailed pin configurations, timing diagrams, absolute maximum ratings, and ordering information for designers.
