The AD7542 is a 12‑bit CMOS multiplying digital‑to‑analog converter designed for direct interface to microprocessors. It features a thin‑film R‑2R ladder, low power dissipation (40 mW max), and small 16‑pin DIP or 20‑terminal surface‑mount packages.
The document provides functional block diagrams, pin configurations, mechanical dimensions, absolute maximum ratings, and detailed electrical specifications such as resolution, gain error, and timing characteristics. Application hints and interface examples for MC6800 and 8085 microprocessors are also included.
