AD5750/AD5750-1 is an industrial current/voltage output driver with programmable ranges. It features various current output ranges and voltage output ranges, high accuracy and stability, flexible serial digital interface, and built-in output fault detection.
The AD5750 and AD5750-1 are low‑cost, single‑channel drivers that provide programmable current or voltage outputs for industrial process‑control and PLC applications. They accept a low‑voltage DAC input and can be configured via a SPI‑ or MICROWIRE‑compatible serial interface.
Key features include multiple programmable output ranges, on‑chip fault detection, PEC error checking, power‑on reset, and the ability to drive both capacitive (1 µF) and inductive (0.1 H) loads. The device operates from a +12 V to +24 V supply and is supplied in a 32‑lead LFCSP package.

| Power supply range (AVDD/AVSS) | +12 V (+10 %) to +24 V (+10 %) |
| Operating temperature range | ‑40 °C to +105 °C |
| Package | 32‑lead, 5 mm × 5 mm LFCSP |
| Serial interface | SPI and MICROWIRE compatible |
| Load capability | Capacitive loads up to 1 µF, inductive loads up to 0.1 H |
| Power‑on reset | Device powers up to 0 V or tristate |
The AD5750 uses a flexible serial digital interface that is SPI‑ and MICROWIRE‑compatible.
It includes a power‑on reset function that sets the outputs to 0 V or tristate, and an asynchronous CLEAR pin can force zero‑scale output.
The driver can handle capacitive loads of up to 1 µF and inductive loads of up to 0.1 H.
The device operates from –40 °C to +105 °C.
