I2C +I2S Audio Codec Stereo Class-D Amp Cap-Free Headphone Amp

The ALC5631Q is a high performance and powerful I2 S codec for portable devices. Multi-function configuration for input and output port can flexible for using. Differential input mode can effective to cancel the common-mode noise for input signal. And single-ended input mode can easy be used for external income signal. With wide range volume control can be used for each path whether analog to digital path, analog to analog path or digital to analog path. An analog input to analog output path is bypass ADC and DAC that can keep original performance to output for income signal. In this bypass mode, can into the ultra low power mode by shutdown unused block. The powerful Auto-Level-Control (ALC) function is for playback and record. For playback, it will keep the same output level when different input level. And prevent the output signal be clipped when speaker power is dropping or huge input signal. For record, it can effective to reduce the background noise for voice recording. Wide range power supply and low power consumption on ALC5631Q is suitable for portable devices. Also 48-ball QFN (6mm x 6mm) package is used by ALC5631Q. 2.
