AFE5801: Characteristics of VCM output

Part Number: AFE5801

Hello,

I'd like to know specifically the SINK current capability of the VCM output on the AFE5801.

Also, there are two VCM pins, are they linked internally or can they sink/source separately ?

thanks

Phil

    Hi Phil,

    How are you?
    The data sheet describes VCM load spec is 3mA (typical).
    Also please look at the User's Guide's schematics.
    It uses CM output (pin 64) to control CH1, CH2, CH3 and CH4 as common mode.
    also uses CM output (pin 17) to control CH5, CH6, CH7 and CH8 as common mode.
    Please follow the way of the User Guide.

    Thank you!

    Best regards,
    Chen
