ADC32RF80: CM pin output drive capability

Part Number: ADC32RF80

Hello,

There is a description of output voltage for CM pin as 1.2V typ but not written current ability. How much can CM pin (pin#22) drive?

We would like to drive 2mA at least but would like to know how much it can drive.

Best regards,

Toshihiro Watanabe

  • Hi,

    Pin 22 is common-mode for the analog input and must be connected to the ground through a capacitor as shown in the application diagram section in the datasheet. It should not be tapped to source current.

    Regards,
