Texas Instruments DAC8750IRHAR
The DAC7750 and DAC8750 are low-cost, precision, fully-integrated 12-bit and 16-bitdigital-to-analog converters (DACs) designed to meet the requirements of industrial process-controlapplications. These devices can be programmed as a current output with a range of 4 mA to 20 mA, 0mA to 20 mA, or 0 mA to 24 mA. The DAC7750 and DAC8750 include reliability features such as CRCerror checking on the serial peripheral interface (SPI™) frame, a watchdog timer, an open circuit, compliancevoltage, and thermal alarm. In addition, the output current can be monitored by accessing aninternal precision resistor.
These devices include a power-on-reset function to ensure that the device powers up in aknown state (IOUT is disabled and in a Hi-Z state). The CLR terminal sets the current output to thelow end of the range if the output is enabled. Program the zero and gain registers to digitallycalibrate the device in the end system. The output slew rate is also programmable by register.These devices can superimpose an externalHART® signal on thecurrent output, and can operate with a 10-V to 36-V supply.
All versions are available in both 40-pin VQFN and 24-pin TSSOP packages.
