Part Number: TPA3144D2

Hello:

TPA3144D2 has a design method to describe the inductance of output filter in datasheet. If using alternative Bead inductance in use process, if you can use the inductance calculation?

Best Regards

Hi Leon,

Please refer datasheet 10.2.2.1 Ferrite Bead Filter Considerations. we recommend to select at least 300ohm @100MHz, and ensure that the rated current can meet the output power requirement.

What's more, the audio THD+N performance is mainly related with magnetic core material. So please select the good linearity beads at audio frequency band.

Rdgs,
Matthew
