The AD7722 is a complete low power, 16-bit, Σ-∆ ADC. The part operates from a 5 V supply and accepts a differential input voltage range of 0 V to +2.5 V or ±1.25 V centered around a common-mode bias. The AD7722 provides 16-bit performance for input bandwidths up to 90.625 kHz.
The AD7722 is a low‑power, 16‑bit, sigma‑delta ADC that operates from a 5 V supply and supports both bipolar and unipolar input ranges. It delivers up to 195.3 kSPS output word rate with an on‑chip 2.5 V reference and offers parallel or serial data interfaces.
The document lists electrical characteristics, absolute maximum ratings, pin functions, timing diagrams, and ordering information for the 44‑lead MQFP package. It also includes detailed specifications such as input bandwidth, power consumption, and reference voltage performance.
