AD5413 Digital-to-Analog Converter

ADI's 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 AV_SS pin to a +33 V maximum on the AV_DD1 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 has an optional SPI cyclic redundancy check (CRC). The AD5413 implements improved diagnostic features from earlier versions of similar DACs.

ADI’s AD5413 is optimized for high accuracy, 14-bit resolution with diagnostics. It is limited to a couple of voltage and current ranges. This allows users to adopt it in price-sensitive markets without overspending on unwanted features.
