Analog Devices AD5749 Datasheet
The AD5749 is a single‑channel industrial current/voltage output driver designed for process‑control and actuator‑control applications. It offers programmable output ranges of 0 mA‑24 mA or 4 mA‑20 mA, selectable via hardware or software, and includes open‑circuit protection for inductive loads.
The device operates from a single supply (AVDD 12 V ±10 % to 55 V) and provides a loop‑compliance voltage of AVDD‑2.75 V. Its serial interface is compatible with SPI and Microwire, supports up to 50 MHz clock rates, and includes optional PEC CRC‑8 error checking for robust communication in industrial environments. This manual is written in Chinese.
