Original question:

PCM6020-Q1: BSTOUT voltage

PCM6020-Q1: BSTOUT

Hi team,

Could you confirm if my understanding below correct?

What is the BSTOUT voltage?   --> 1V above set MICBIAS voltage.

How much is the BSTOUOT switching frequency --> 6.144MHz (at fs=48kHz) or 5.6MHz(at fs=44.1kHz)

regards,

    Hi Shinji-san,

    Your assumptions are correct. The BSTOUT switching frequency can also change to an internal 5MHz oscillator if the ADC channels are not active, but it will switch to match the ADC modulator clock when ADC channels are active to avoid the possibility of interfering with the modulator.

    Best,

    Zak
