TPA3221: Recommended Input AC-Coupling Capacitors

Sadanori Kato

Part Number: TPA3221

Hi,

Are there any side effects if the input ac-coupling capacitors are larger than the recommended value which is mentioned in TPA3221 data sheet ?

Hi Sadanori-san,

Usually we aren't as concerned with increasing the capacitance compared to decreasing. By increasing it you will lower the cuf-off frequency of the high pass filter which is fine since it's not in the audio band.
