Forum Post: PCM1680,PCM1681 - output from Vcom

HI All,

Would you mind if we ask PCM1680, PCM1681?

<Question>
The datasheet on P28 shows, "If Vcom pin is to be used to bias external ciruitry, a voltage follower is required for buffering purpose." 
Is it possible to connect 20kΩ to Vcom1 directly?(In oeder to connect the input of OP-Ampifier with 20kΩ.)
If it is not possible, we will use a voltage follower.

Kind regards,

Hirotaka Matsumoto
