TLV320AIC3212: Class-D Speaker Output Filter

Part Number: TLV320AIC3212


On our design based on tlv320aic3212, we are connecting a mono 8ohm(800mW) speaker at SPKLP/M. Can the speaker be connected directly to the class-d output as given on the TLV320AIC3212EVM-U?

Do we require an L-C filter at the class-D output from the audiocodec?

We observed that the speaker is getting heated when playing audio. The heating is observed on the EVM as well.
