AD7676 is a 16-bit, 500kSPS, differential ADC with ±1 LSB INL.
The AD7676 is a 16‑bit, charge‑redistribution SAR analog‑to‑digital converter that operates from a single 5 V supply. It provides up to 500 kSPS throughput, 16‑bit resolution with no missing codes, and low power consumption (67 mW typical, 15 µW in power‑down). The device supports both parallel (8‑ or 16‑bit) and 2‑wire serial interfaces, compatible with 3 V or 5 V logic levels.
The datasheet includes detailed specifications, timing diagrams, pin‑function tables, definition of performance metrics, typical performance graphs, and ordering information for the LQFP and LFCSP packages. It also outlines absolute maximum ratings and recommended ESD precautions.
