Product Details

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 AVSS to +33 V maximum on AVDD1. The CHART pin 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 Highlights

  1. 16-bit performance.
  2. Range of diagnostic features.
  3. Integrated 12-bit monitoring ADC.
  4. HART compliant.

Applications

  • Process control
  • Actuator control
  • Channel isolated analog outputs
  • Programmable logic controller (PLC) and distributed control systems (DCS) applications
  • HART network connectivity
