USB OTI2172

The main system block consists of CD Solution (LC78692 Pack), MICOM (LC87F5CC8A), ADC+FUNCTION IC (AK5367). AK5367 performs stereo A/D conversion with analog audio input such as AUX1, AUX2, MIC, TUNER. The The sampled digital data transmitted by I2S format to PS9829. AMP block consists of PS9829, 3 TAS5152 and other passive component for Low Pass Filter. The PS9829 transforms PCM to PWM signal and TAS5152 amplify this signal to drive total 680W.
