Working Principles

The AK5373EQ operates by converting analog audio signals into digital format using its built-in ADC (Analog-to-Digital Converter). It then processes the digital audio data using various algorithms to enhance the audio quality. The processed audio is then converted back to analog format using the DAC (Digital-to-Analog Converter) and sent to the output channels.

Application Field Plans

The AK5373EQ is suitable for a wide range of audio applications, including:

1. Professional audio recording equipment
2. Portable audio devices
3. Automotive audio systems
4. Home theater systems
5. Telecommunications equipment
