  • DAC8718: device heating up (when negative voltage AVss applied)

    Resolved
    Part Number: DAC8718 Other Parts Discussed in Thread: DAC7718 , Team, this is a continuation of the previous thread about DAC7718 heating up to 45 degrees C when the negative -5V voltage is applied to AVss (through a 1kOhm resistor). We now use DAC8718…
