DESCRIPTION
Using the NS4168's I2S digital audio serial interface to transmit to the amplifier, the impact of the noise source on the transmitted audio can be significantly reduced. In addition, it also avoids the noise caused by the built-in audio decoding DAC of the MCU master chip, and finally obtains a higher signal-to-noise ratio and a smaller distortion degree.
