Texas Instruments DACx750 Programmable Current Output DACs
Texas Instruments DACx750 Single-Channel Programmable Current Output DACs are precision, fully-integrated 12-bit and 16-bit digital-to-analog converters (DACs) designed to meet the requirements of industrial process-control applications. These devices can be programmed as a current output with a range of 4mA to 20mA, 0mA to 20mA, or 0mA to 24mA. The DACx750 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.
