The AD677 is a multipurpose 16-bit serial output analog-to-digital converter which utilizes a switched-cap technology. It provides excellent dc performance and ac performance, making it suitable for a wide range of applications.
The AD677 is a multipurpose 16‑bit analog‑to‑digital converter featuring on‑chip autocalibration, a sample‑hold function and separate analog and digital grounds for reduced crosstalk. It operates from +5 V and +12 V supplies and is available in plastic DIP, ceramic DIP and SOIC packages.
The device uses a charge‑redistribution capacitor array and successive‑approximation conversion, providing -99 dB THD, 92 dB S/(N+D) and up to 100 kSPS sampling. Detailed specifications, pin descriptions, timing diagrams and ordering information are included.
