AD5750:  Industrial Current/Voltage Output Driver, Programmable Ranges

Product Description

The AD5750 is a single channel, low-cost, precision, voltage/current output driver with hardware or software programmable output ranges. The software ranges are configured via an SPI/Microwire compatible serial interface. The AD5750 targets applications in PLC and industrial process control. The analog input to the AD5750 is provided from a low voltage, single supply digital-to-analog converter and is internally conditioned to provide the desired output current/voltage range.

The output current range is programmable across five current ranges - 4–20mA, 0–20mA or 0–24mA, ±20ma and ±24ma. Voltage output is provided from a separate pin that can be configured to provide 0V to 5V, 0V to 10V, ±5V or ±10V output ranges. An over-range of 20% is available on the voltage ranges.

Analog outputs are short and open circuit protected and can drive capacitive loads of 1uF and inductive loads of 0.1H. The device is specified to operate with a power supply range from ±12 V to ±24 V. Output loop compliance is 0 V to AVDD – 2.5 V.

The flexible serial interface is SPI and MICROWIRE compatible and can be operated in 3-wire mode to minimize the digital isolation required in isolated applications. The interface also features an optional PEC error checking feature using CRC-8 error checking, useful in industrial environments where data communication corruption can occur.

The device also includes a power-on-reset function ensuring that the device powers up in a known state and an asynchronous CLEAR pin which sets the outputs to zero-scale / mid-scale voltage output or the low end of the selected current range.

A HW SELECT pin is used to configure the part for hardware or software mode on power up.

The total output error is typically ±0.1% in both current mode and voltage mode.
