PCM4201 and PCM1774 with DC

Other Parts Discussed in Thread: PCM4201, PCM1774

Hi All,

Would you mind if we ask PCM4201 and PCM1774?

<Question>
These PCM4201 and PCM1774 are used for audio(AC) generally.
However, if we use as DC signal(0Hz), are these devices available to use DC signal? or not?

1. PCM4201 input : DC input
2. PCM1774 output : DC output

Kind regards,

Hi, Matsumoto-san,

Unfortunately, we do not have any information on using either of these devices for DC signals.

Hi Don San,

Thank you for your reply!
And then, if you know followings, please let us know.

<ADC PCM4201>
When we use DC connection without Input Buffer, is it possible to use DC-connection?
Then, HPF is disable(Bypass).

<DAC PCM1774>
When we use I2S, the is it possible to use DC-connection for output?

kind regards,
