The AD7543 is a 12‑bit monolithic CMOS multiplying DAC designed for serial‑interface applications. It features a 12‑bit shift register, a DAC input register, and an asynchronous CLEAR input for easy initialization. The device is supplied with a +5 V supply and is available in 16‑pin DIP, 20‑terminal LCCC and PLCC packages.
The datasheet provides detailed specifications, pin configurations, functional block diagrams, absolute maximum ratings, and application notes including interface examples for MC6800 and 8085 microprocessors. Guidance on ground management, output amplifier selection, and high‑frequency considerations are also included to help designers achieve optimal performance.
