The AK4385ET is one of the most advanced audio codecs currently available on the market. As a special purpose ADC/DAC, the AK4385ET is designed to provide a complete audio solution for a variety of applications. It features advanced functions such as sample rate conversion, equalization, and volume control.

Applications for the AK4385ET include portable audio systems, multimedia platforms, wireless audio streaming, and other audio-intensive applications. Its sample rate conversion, equalization, and stereo enhancement capabilities enable a wide range of audio applications. It also offers an enhanced audio performance with low power consumption, making it ideal for battery-operated equipment.

The AK4385ET’s working principle centers on its stereo codec. The codec converts digital audio information into an analogue signal, and vice versa. This conversion is facilitated through use of the AK4385ET’s sample rate converters, equalizers, and sound processors. The A/D converter samples digital audio at the input of the codec, while the D/A converter converts digital audio from the codec’s output back to analogue. The codec’s sample rate converters are responsible for converting digital audio from its original sample rate to the desired final rate. The equalizers and sound processors then adjust the audio to its desired acoustic qualities.

The AK4385ET’s sample rate converters employ a high-precision delta-sigma modulator to provide excellent spectral response and distortion characteristics. The delta-sigma modulator operates by taking the analogue audio input and converting it into a digital signal. The modulator then “samples” the digital audio before outputting it in the desired sample rate. The equalizers and sound processors employ digital signal processing (DSP) algorithms to manipulate the audio and apply the desired acoustic qualities.

The AK4385ET is a versatile and feature-rich audio codec tailored to a variety of audio applications. Its high-performance audio capabilities, along with its low power consumption, make it well-suited for a variety of portable and multimedia audio devices. With its advanced features and working principle, the AK4385ET is truly a unique and powerful audio solution for today’s audio applications.
