Part Number: TPA3144D2 Hi team,
My customer would like to use TPA3144D2 device for max 4W speaker. Could you please help to analyze whether attached Ferrite Bead could be used? In addition, the Ferrite Bead is used along with a 1000pF capacitor. Thanks…
Part Number: TPA3144D2 Hi
I would like to use the TPA3144D2 (12V supply, 20dB gain) to drive a 5W 8ohm speaker. I think the power of the PBTL mode will be to much, so i plan to use just one channel. What should i do with the unused channel in- and output…
Part Number: TPA3144D2 Hello
Below is Class D LC filer calculate formula. But if add bead not L on output of TPA3144D2, the LC filer formula could be used to calculated by bead ? or has any filter formula by bead+cap for filer design? Thank you.

Part Number: TPA3140D2PWPEVM Other Parts Discussed in Thread: TPA3144D2 , TPA3140D2 Hello Team,
I see that the TPA3144D2 IC does not have a EVM, is it possible to use the tpa3140d2pwpevm but switch out the IC for the TPA3144D2. Looking at the datasheet…

Hi Team, Can TPA3144 drive the 16ohm speaker around 5Watt at THD 1% under PVDD 12V?
If not, what is the THD at 5Watt/16ohm speaker?
BR, SHH.
