Working Principle

The PCM2900CDB works using electronic switching techniques. It takes the analog signal and converts it into a digital one using an analog-to-digital converter (ADC). This digital signal is then processed by the codec’s internal processor to enhance the audio quality. The digital signal is then passed through a digital-to-analog converter (DAC) that converts the digital signal back into an analog waveform which is then passed through an amplifier for output. The PCM2900CDB also provides for the programming of various codec parameters such as sample rate, bit resolution, minimum and maximum frequencies.

Conclusion

The PCM2900CDB is an ideal cost-effective solution for audio equipment, with support for low-power I²C interface and full-function mode. It is suitable for portable audio applications and provides a wide range of features and benefits that make it a great choice for any audio-related application. With its wide range of features and benefits, the PCM2900CDB can provide you with the best audio experience.
