AD5750 is a single channel, low-cost, precision, voltage/current output driver produced by Analog Devices. It has multiple output current/voltage ranges to meet the needs of different application scenarios. The input of the driver is a single-ended digital signal, which can be configured through the I2C interface. AD5750 has overcurrent protection, PEC error checking, and clear functions to improve system safety and reliability.
The AD5750 is a single‑channel, precision voltage/current output driver with programmable ranges. It supports both current (4‑20 mA, 0‑20 mA, 0‑24 mA, +20 mA, +24 mA) and voltage (0‑5 V, 0‑10 V, +5 V, +10 V) output modes and communicates via an SPI/Microwire compatible serial interface.
The document provides detailed specifications, timing characteristics, pin descriptions, layout guidelines, and isolation options, helping designers integrate the device into PLC and industrial process‑control applications.
| Current Output Ranges | 4‑20 mA, 0‑20 mA, 0‑24 mA, +20 mA, +24 mA |
|---|---|
| Voltage Output Ranges | 0‑5 V, 0‑10 V, +5 V, +10 V (20 % over‑range available) |
| Power Supply Range (AVop/AVss) | +12 V to +24 V (±10 %) |
| Operating Temperature Range | -40 °C to +105 °C |
| Short‑Circuit Current | 15 mA max |
| Digital Input Supply (DVce) | 2.7 V to 5.5 V |
The AD5750 can output 4‑20 mA, 0‑20 mA, 0‑24 mA, +20 mA or +24 mA, selectable via software.
The device operates from a dual supply of +12 V to +24 V (±10 %) on AVop/AVss.
External power diodes and a surge‑current‑limiting resistor can be added to keep the output within the AVop‑2 V compliance limit during transients.
The device limits short‑circuit current to 15 mA max.
