Working Principles

The PCM1803ADBG4 utilizes delta-sigma modulation to convert analog audio signals into digital format. It employs oversampling techniques to achieve high resolution and accuracy. The input audio signal is sampled at a high frequency and then processed through a digital filter to remove unwanted noise and artifacts. The resulting digital signal is then outputted in serial format.

The PCM1803ADBG4 is suitable for various applications that require high-quality audio conversion, such as:

1. Professional audio recording equipment
2. Digital mixing consoles
3. Audio interfaces for computers
4. Home theater systems
5. Musical instruments and effects processors
6. Automotive audio systems
