  • DAC8571: Used as a one-quadrant multiplying DAC

    Resolved
    Part Number: DAC8571 Hi team, The reference voltage of DAC8571 is 0 ~ VDD. One of our customers asked whether it can be used as a one-quadrant multiplying DAC? VREF voltage input range is 0-1V and signal frequency is 1kHz. Best Regards, Amy Luo

  • DAC8571: Capacitive load stability

    Resolved
    Part Number: DAC8571 Hi Team, The datasheet shows the following about OUTPUT CHARACTERISTICS. Does it mean we should put 1000pF when RL=2kΩ? Or does it mean maximum capacitance to set stable? I would like to ask about a value of feedback resister in…
