NS4168 Description
NS4168 is a mono class D audio power amplifier with I2S serial digital audio input and NCN output. It has built-in digital-to-analog converter (DAC) and multistage Class D modulator for excellent audio performance. 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.
