Since this is a Japanese IC it will probably use the Sony format and the easiesy way is to use TDA1543A.iF You use tda1543 you need a circuit to make I2S( philips ) signal compatible to tda1543.That is EIAJ to I2S.Search the threads and you will find the circuit.
Hi,
& didn't find MN672212 datasheet .& connected via I2S 3 pins.With TDA1543 there is no sound,with TDA1543A sound level very low,but nice. & think maybe TDA1543A have protection diodes at the output like most parallel dacs.
