Introduction

ADAV803ASTZ-REEL is a long-distance, low noise, low-power codec designed to convert between analog electrical signals and digital audio signals, making it suitable for audio applications, such as headsets and cellular phones. In addition to its low-power, low-noise design, the ADAV803ASTZ-REEL also features adjustable gain, adjustable input and output levels, and improved dynamic range.

Application Field

ADAV803ASTZ-REEL is suitable for both home and professional audio applications, such as headsets, cell phones, wireless microphones and digital audio recorders. It is also used in consumer digital audio systems, such as CD and DVD players, where it is used to convert analog audio signals to digital audio and vice versa.The codec supports an output signal-to-noise ratio (SNR) of 96 dB and maximum total harmonic distortion (THD) of 0.03%. It has a frequency response of 30 Hz to 20 kHz and a power consumption of 1.2 watts.

Working Principle

The ADAV803ASTZ-REEL converts analog audio signals to digital audio signals using a process called pulse-code modulation (PCM). This process takes an analog signal and encodes it as a series of digital words.The analog signal is sampled at a rate determined by the sampling frequency. The resulting digital signal is then quantized and filtered to reduce noise and distortion. Finally, the digital audio is sent to the output device or recorded on a digital storage medium.At the other end of the transmission, the ADC codec can be used to convert digital audio signals to analog signals. This process is the reverse of what is described above. The digital audio is decoded and then filtered and quantized. The filtered and quantized digital audio is then sent to an analog output device such as speakers, headphones or other audio peripherals.

Conclusion

In conclusion, the ADAV803ASTZ-REEL is a versatile and powerful codec that can be used for a variety of audio applications. It is a low-power and low-noise device that features adjustable gain, adjustable input and output levels, and improved dynamic range. The codec supports high-quality audio conversion from analog to digital and from digital to analog.
