(HART) signal to be coupled on the current output. The AD5423 uses a versatile, 4-wire, serial peripheral interface (SPI) that operates at clock rates of up to 50 MHz and is patible with standard SPI, QSPI™, MICROWIRE™, digital signal processor (DSP), and microcontroller interface standards. The interface also features an optional SPI cyclic redundancy check (CRC) and a watchdog timer (WDT). The AD5423 offers improved diagnostic features from earlier versions of similar DACs, such as an integrated, 12-bit diagnostic analog-to-digital converter (ADC).
