Part Number: TAS5707
Other Parts Discussed in Thread: TAS5717,

Hi Team,
Can custome use 39nF/50V to replace 33nF for the bootstrap design on TAS5717 due to cap supply shortage? Any side effect?

SHH,

This should be fine but I would check the design using an EVM or similar first. As long as the audio performance matches, the small shift should be fine.

Hi Adam,
Competitor's datasheet will indicate the min and max boostrap cap values.
