The document provides information about the AD5749 industrial current output driver. The product features a single-supply design, a maximum supply of 55V, and programmable ranges.
The AD5749 is a low‑cost, precision, single‑channel current‑output driver designed for PLC and industrial process‑control applications. It accepts a 0‑4.096 V analog input and provides programmable current ranges via a SPI/MICROWIRE‑compatible serial interface.
Key features include two selectable current ranges (0‑24 mA or 4‑20 mA), a wide power‑supply range of 12 V to 55 V, on‑chip fault detection, PEC error checking, and an asynchronous CLEAR function. The device can drive inductive loads up to 0.1 H and operates from –40 °C to +105 °C.
