The MX7543 is a high‑precision 12‑bit CMOS serial‑input digital‑to‑analog converter that operates from a single +5 V supply and dissipates about 450 mW. It offers excellent gain stability, low feedthrough error, and a range of package options for applications such as remote analog systems, robotics, automatic test equipment, and calibration systems.
The document includes absolute maximum ratings, detailed electrical characteristics, functional block diagrams, interface logic timing, and application notes on grounding, compensation, and output amplifier selection. It also provides recommended component values and layout guidelines for optimal linearity and dynamic performance.
