DAC7750

DAC7750, DAC8750 SBAS538D – DECEMBER 2013 – REVISED DECEMBER 2021 DACx750 Single-Channel, 12-Bit and 16-Bit Programmable Current Output Digital-to-Analog Converters for 4-mA to 20-mA Current-Loop Applications 1 Features 3 Description Current output options: – 0 mA to 24 mA – 4 mA to 20 mA – 0 mA to 20 mA ±0.1% FSR typical total unadjusted error (TUE) DNL: ±1 LSB maximum Maximum loop compliance voltage: AVDD – 2 V Internal 5-V reference: 10 ppm/°C (maximum) Internal 4.6-V power-supply output CRC frame error check Watchdog timer Thermal alarm Open-circuit alarm Pins to monitor output current On-chip fault alarm User-calibration for offset and gain Wide temperature range: –40°C to +125°C Packages: 6-mm × 6-mm 40-pin VQFN and 24-pin HTSSOP 2 Applications Analog output module CPU (PLC controller) Flow transmitter Other sensor transmitter Actuator Process analytics (pH, gas, concentration, force and humidity) DVDD DVDD-EN REFOUT The DAC7750 and DAC8750 (DACx750) are lowcost, 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 ranges of 4 mA to 20 mA, 0 mA to 20 mA, or 0 mA to 24 mA. The DACx750 include reliability features such as CRC error checking on the SPI frame, a watchdog timer, an open circuit, compliance voltage, and thermal alarm. In addition, the output current ...
