The software ranges are configured via an SPI-/MICROWIRE™-patible serial interface. The AD5750/AD5750-1/AD5750-2 target applications in PLC and industrial process control. The analog input to the AD5750/ AD5750-1/AD5750-2 is provided from a low voltage, single-supply digital-to-analog converter (DAC) and is internally conditioned to provide the desired output current/voltage range. Analog input ranges available are 0 V to 2.5 V (AD5750-1/AD5750-2) or 0 V to 4.096 V (AD5750). The output current range is programmable across five current ranges: 4 m A to 20 m A, 0 m A to 20 m A, 0 m A to 24 m A, ±20 m A, and ±24 m A. An overrange of 2% is available on the unipolar current ranges. Voltage output is provided from a separate pin that can be configured to provide 0 V to 5 V, 0 V to 10 V, ±5 V, or ±10 V output ranges. An overrange of 20% is available on the voltage ranges. Analog outputs are short-circuit and open-circuit protected and can drive capacitive loads of 1 µF and inductive loads of 0.1 H. The devices are specified to operate with a power supply range from ±12 V to ±24 V....
