Working Principles

The PCM1802DBR utilizes a delta-sigma modulation technique to convert analog audio signals into digital format. It employs an oversampling technique to achieve high resolution and low noise performance. The input audio signal is sampled at a high frequency, and the resulting bitstream is then filtered and decimated to obtain the desired digital output.

Detailed Application Field Plans

The PCM1802DBR is commonly used in various audio-related applications, including:

1. Audio recording devices: Enables high-quality audio capture in portable recorders, mixers, and audio interfaces.
2. Consumer audio products: Provides accurate audio conversion in CD players, home theater systems, and soundbars.
3. Musical instruments: Allows for precise digitization of musical instrument sounds in electronic keyboards and synthesizers.
4. Automotive audio systems: Enhances the audio quality in car audio systems, providing a more immersive listening experience.
