Description

The AD5423 is a single-channel, voltage and current output digital-to-analog converter (DAC) that operates with a power supply range from −33 V minimum on AVSSto +33 V maximum on AVDD1. The CHARTpin enables a Highway Addressable Remote Transducer®(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 compatible 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).Product Highlights16-bit performance.Range of diagnostic features.Integrated 12-bit monitoring ADC.HART compliant.ApplicationsProcess controlActuator controlChannel isolated analog outputsProgrammable logic controller (PLC) and distributed control systems (DCS) applicationsHART network connectivity
