  • DAC8775: 4-20mA output Issue - incorrect Analog Output

    Part Number: DAC8775 Hello TI team, I'm working with the DAC8775IRWFT (using an STM32 Nucleo board) and running into issues with the 4-20mA current output functionality. I've conducted two tests using two separate ICs and observed different results…

  • DAC8775: The Settling Time issue for DAC8775

    TI Thinks Resolved
    Part Number: DAC8775 Tool/software: Hi, We use the DAC8775 in our PLC AO-module project. Now we test the Settling Time of DAC8775 but the waveform is about more than 1ms, it is slow that it is only 15-30us in the datasheet, please kindly review our…

  • DAC8775: 4–20 mA Configuration – Unable to Reach Full-Scale 20 mA Output

    Part Number: DAC8775 Tool/software: Hi, I am working with the DAC8775 in a 4–20 mA output configuration. The output current range is configured correctly, and the DAC output scales linearly. However, the maximum current I’m able to achieve is around…

  • DAC8775: Alarm Pin & Status Bit Observed Contradictions

    TI Thinks Resolved
    Part Number: DAC8775 Tool/software: TI, I’ve read through the datasheet for the DAC8775, but I’m a bit confused about the behavior I’m observing. I’m using the positive buck-boost configuration with a 0–20 mA output on channel C. According to the…
