The AK5371A is a special purpose analog to digital converter (ADC) designed to convert high quality audio signals. It features a low power 24-bit delta-sigma converter with a sampling rate of up to the 192kHz and supports sampling rates from 32kHz to 192kHz in 6dB increments. The AK5371A contains several features such as an input mute time of 8ms, a dynamic range of up to 104dB, and low power consumption.

Application Field of AK5371A

The AK5371A is well suited for use in high quality audio applications such as ADAT and S/PDIF where high quality audio playback is essential. It can also be used in professional audio equipment for recording and post-production applications. In addition, the AK5371A can be used in digital audio applications such as digital television, DVD, digital radio, broadcast and satellite audio systems.

Working Principle of AK5371A

The working principle of the AK5371A consists of a 24-bit delta-sigma modulator and a low power digital decimator. The delta-sigma modulator uses the sampling rate to convert analog signals into digital signals. The modulator then performs a sequence of operations to convert the analog signal into a digital signal. After the conversion, the digital decimator is used to reduce the sampling rate of the digital signal.

The AK5371A supports a flexible output format with selectable output data widths and supports several output frequency rates. It also supports several analog input formats, including analogue input signal, digital mic and line level input. The modulator also incorporates a low noise signal path with a dynamic range of up to 104dB. The AK5371A also includes an internal mute time of 8ms to reduce noise during signal transitions.

Conclusion

In conclusion, the AK5371A is a special purpose ADC designed for high quality audio applications. It features a low power 24-bit delta-sigma converter with a sampling rate of up to the 192kHz and supports sampling rates from 32kHz to 192kHz in 6dB increments. The AK5371A can be used in professional audio equipment for recording and post-production applications, as well as digital audio applications such as digital television, DVD, digital radio, broadcast and satellite audio systems.
