The AD5737 is a four-channel, current-output DAC that operates from a 10.8 V to 33 V supply. The on-chip dynamic power control function is based on a DC-DC boost converter optimized for the lowest on-chip power consumption, and can regulate the voltage of the output driver from 7.4 V to 29.5 V to minimize package power consumption.
Each channel has a corresponding CHART pin, so the HART signal can be coupled to the current output of the AD5737.
The AD5737 features a versatile three-wire serial interface capable of operating at clock rates up to 30MHz and is compatible with standard SPI, QSPI™, MICROWIRE®, DSP, and microcontroller interface standards. The serial interface also offers optional CRC-8 packet error checking, as well as a watchdog timer to monitor interface activity.
For a 16-bit equivalent solution, check out the AD5757. For voltage and current configurable versions, check out the AD5755, AD5755-1, or AD5735.
