TLV320AIC3204的class-D模式下驱动立体声耳机的外部电路配置

Other Parts Discussed in Thread: TLV320AIC3204

Hi,为了降低codec的功耗,需要把默认的耳机驱动从Class AB改为Class-D模式,在TLV320AIC3204 Application Reference Guide Reference Guide中的第P14-P15页有提到class-d的耳机驱动,但无详细的外围配置电路,只有一个需要增加LC(82uH和1uF)的LPF示意图,请问这个外部的LC是直接连接在原有的HPL和HPR端口吗?请问下图的立体声耳机(16 ohm)配置是否正确,谢谢!
