ANALOG DEVICES AD5422BCPZ-REEL7 Digital to Analogue Converter, 16 bit, 3 Wire, Microwire, QSPI, Serial, SPI, 10.8V to 40V, LFCSP

AD5422 is a single channel, 16bit, fully integrated digital-to-analogue converter (DAC). It is programmable current source and programmable voltage output designed to meet the requirements of industrial process control applications. The device operates with an AVDD power supply range from 10.8V to 40V and has current loop compliance voltage (AVDD) from 0V to ? 2.5V. 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 device powers up in a known state. The part also includes an asynchronous clear pin (CLEAR) that sets the outputs to zero-scale/midscale voltage output or the low end of the selected current range. This DAC is widely used in application such as process controls, actuator controls, PLC etc.
