The DAC7750IPWP is a precision fully-integrated 16-bit Digital-to-analog Converter (DAC) designed to meet the requirements of industrial process-control applications. The DAC7750 includes reliability features such as CRC error checking on the serial peripheral interface (SPI™) frame, a watchdog timer, an open circuit, compliance voltage and thermal alarm. In addition, the output current can be monitored by accessing an internal precision resistor. This device includes a power-on-reset function to ensure that the device powers up in a known state. The CLR terminal sets the current output to the low end of the range if the output is enabled. Program the zero and gain registers to digitally calibrate the device in the end system. The output slew rate is also programmable by register. This device can superimpose an external HART® signal on the current output and can operate with a 10 to 36V supply.
