Overview
APA3175 20W Stereo Digital Class-D Audio Power Amplifier with EQ and DRC Features General Description • Operating Voltage: 4.
5V~24V for PVDD The APA3175 is a digital input, stereo, high efficiency, – 3.
0V~3.
6V for DVDD and AVDD • High Efficiency Class-D Operation Eliminate the Class-D audio amplifier available in a TQFP7x7-48P package.
Need of Heatsinks The APA3175 accepts the digital serial audio data and • Digital Serial Audio Input (Stereo Output) using the digital audio processor to convert the audio • I2C Control Interface data becomes the stereo Class-D output speaker • Sampling Rate can Support from 32kHz to 192kHz amplifier.
This provides the seamless integration between • Separated Volume Control from 24dB to Mute the codec and the speaker amplifier.
