The AD5413 is a single-channel, 14-bit voltage and current output, digital-to-analog converter (DAC) that operates within a power supply range from a −33 V minimum on the AVSS pin to a +33 V maximum on the AVDD1 pin.
The CHART pin enables a highway addressable remote transducer (HART®) signal to be ac-coupled on the current output.
The AD5413 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 SPI interface has an optional SPI cyclic redundancy check (CRC). The AD5413 implements improved diagnostic features from earlier versions of similar DACs.
