The AD676 is a 16-bit 100 kSPS sampling ADC. It has automatic calibration, parallel output format, 16 bits, no missing codes, -1LSB INL, -97dB THD, 90dB S/(N+D), 1MHz full power bandwidth and other features.
The AD676 is a multipurpose 16‑bit analog‑to‑digital converter that uses a switched‑capacitor charge‑redistribution architecture to achieve a 100 kSPS conversion rate (10 µs total conversion time). It features on‑chip autocalibration, a parallel output format, and specifications such as –97 dB THD and 90 dB S/(N+D).
The device is offered in a 28‑pin plastic DIP or 28‑pin side‑brazed ceramic package, with detailed pin descriptions, timing diagrams, and ordering information. The datasheet provides full AC, DC, and timing specifications, absolute maximum ratings, and mechanical dimensions.
