AD5422:  Single Channel, 16-Bit, Serial Input, Current Source & Voltage Output DAC

Product Description

The AD5422 is a low-cost, precision, fully integrated 16-bit digital-to-analog converters (DAC) offering a programmable current source and programmable voltage output designed to meet the requirements of industrial process control applications.

The output current range is programmable at 4 mA to 20 mA, 0 mA to 20 mA or an overrange function of 0 mA to 24 mA.

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 10% is available on all ranges.

Analog outputs are short and open circuit protected and can drive capacitive loads of 1 μF.

The device is specified to operate with a power supply range from 10.8 V to 40 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 device also includes a power-on-reset function ensuring that the device powers up in a known state. The part also includes a asynchronous clear pin (CLEAR) which sets the outputs to zero-scale/midscale voltage output or the low end of the selected current range.

The total output error is typically ±0.1% in current mode and ±0.01% in voltage mode.
