TLV320AIC32: Class AB to Class -D

Hi Diljith,

That is, the need to add LC filter mentioned in pages 14-15 of the reference design,Is the LC filter directly connected to the HPL and HPR pins?

Figure 2-6 and 2-7 show whether the op amp in front of the LC filter is an internal CODEC op amp or an external op amp needs to be added.

Thanks

Hi Neal,

The performance of the Class-D headphone amplifier mode on the AIC3254 is not as good as the Class AB mode. For audio applications we would recommend using the Class AB amplifier. Could you let us know what kind of transducer (or load) are you trying to driver with the Class-D mode?

Best Regards.
