AD5422AREZ-REEL

AD5422 is a single channel 16bit, monotonicity, serial input, current source and voltage output DAC, HART connectivity. This offering a programmable current source and programmable voltage output designed to meet the requirements of industrial process control applications. The LFCSP version of this product has a CAP2 pin so that the HART signals can be coupled onto the current output of the AD5422. Voltage output is provided from a separate pin that can be configured to provide 0V to 5V, 0 V to 10V, ±5V, or ±10V output ranges. Analog outputs are short and open-circuit protected and can drive capacitive loads of 1µF. 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. Application includes process controls, actuator controls, PLC.
