Hi,

Is my understanding correct that Vcom pin(7 pin) can be used to bias the external filters such as PCM1754?

Best regards,

Hello Kato-san,

You are correct, the VCOM node can be used to bias external circuitry. Note that similarly to the PCM1754, this node is high-impedance and has limited current drive capability. You will still need to buffer the output if there is any current load.

Thanks,

Paul
