DAC7563: Analog output voltage have an AC signal

Part Number: DAC7563

Analog output voltage have an AC signal, Changing the output can affect frequency and Vpp.

Is there any possibility to cause this problem?

  • Hi Alan,

    Do you have a capacitive load on the output? That could cause oscillation, as the output is essentially an OPAMP. Also, please verify if your power supply is stable and your grounds are connected.

    Thanks!

    Remove the capacitor, test OK, thank you!!
