The AD5751 is a single-channel, low-cost, precision, voltage/current output driver with hardware or software programmable output ranges. The software ranges are configured via the I2C interface. The AD5751 features low output voltage drift (5 ppm/°C) and a wide operating temperature range (-40°C to +105°C).
The AD5751 is a low‑cost, precision I/V output driver that provides programmable voltage and current ranges (0‑5 V, 0‑10 V, 0‑40 V; 4‑20 mA, 0‑20 mA, 0‑24 mA). It communicates via an SPI/Microwire‑compatible 3‑wire serial interface and includes features such as on‑chip fault detection, PEC error checking, power‑on‑reset and an asynchronous CLEAR pin.
The device operates from a 12 V to 60 V supply, supports capacitive loads up to 1 µF and inductive loads up to 0.1 H, and offers high accuracy with a total unadjusted error of 0.1 % (FSR). It is intended for industrial process and actuator control applications and includes layout and transient‑voltage protection guidelines for reliable integration.
