Hi
We are testing TPA3138D2 EVM with it original circuit output filter is Ferrite Bead and see 2.4% THD+N at 12V and 6 ohm speaker condition (BTL) .
The TPA3138D2 datasheet fig. 5 show 12V and 6 ohm speaker it can achieve 10W 1% THD+N.
1. May i check datasheet fig.5 test circuit. what is the L and C value for the output filter ?
2. Any idea higher THD+N % when using Ferrite Bead at the output ?
Below attached our EVM test result for reference!
