The software ranges are configured via an SPI-/MICROWIRE™-compatible 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 mA to 20 mA, 0 mA to 20 mA, 0 mA to 24 mA, ±20 mA, and ±24 mA. 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. Output loop compliance is 0 V to AVDD − 2.75 V. The flexible serial interface is SPI and MICROWIRE compatible and can operate in 3-wire mode to minimize the digital isolation required in isolated applications. The interface also features an optional PEC feature using CRC-8 error checking, useful in industrial environments where data communication corruption can occur. The devices also include a power-on-reset function, ensuring that the devices power up in a known state (0 V or tristate), and an asynchronous CLEAR pin that sets the outputs to a zero scale/midscale voltage output or the low end of the selected current range. The HW SELECT pin is used to configure the parts for hardware or software mode on power-up. Table 1.
