The document describes the features and characteristics of ADI products from BDTI C company.
The AD7547 is a dual 12‑bit current‑output DAC that includes on‑chip level shifters, data registers and control logic for easy microprocessor interfacing. It offers 4‑quadrant multiplication, low gain error, and fast interface timing, making it suitable for test equipment, audio, synchro, and process‑control applications.
The document provides a functional block diagram, pin‑out tables, timing characteristics, electrical specifications, and example circuits for both unipolar and bipolar operation. It also includes layout recommendations, microprocessor interface examples for 8086 and 68000, and application hints such as programmable state‑variable filters and single‑supply operation.
