Working Principles

PCM3000E operates by converting analog audio signals into digital format using an ADC (Analog-to-Digital Converter). It then processes the digital audio data and converts it back to analog format using a DAC (Digital-to-Analog Converter). The processed audio can be output through the Line-Out or Headphone-Out channels. The chip communicates with the host system through the digital interfaces (I2S/SPI) for control and data transfer.

Detailed Application Field Plans

  • Portable audio devices such as MP3 players, smartphones, and tablets.
  • Audio recording equipment and mixers.
  • Automotive infotainment systems.
  • Home entertainment systems and multimedia speakers.
  • Gaming consoles and virtual reality devices.
