AK4424ET

The AK4424ET is a high-performance stereo audio digital-analog converter (DAC) developed by Asahi Kasei Microdevices Corporation. It features advanced signal processing and noise inhibition compatibility, allowing for excellent audio fidelity, and provides designers with a variety of tools for optimizing sound response. The product is designed to operate from 8kHz up to 192kHz sampling rates, supporting a range of audio resolution up to 32-bit. The AK4424ET also integrates multiple features that are essential for audio applications including a dedicated low-noise headphone amplifier, individual mute control for each channel, as well as a versatile range of digital filter and feedback features.

The AK4424ET is perfectly suited for a wide range of applications including portable audio and instrumentation speakers, compressed audio systems, home theater systems, and many more. Its features make it a preferred option for anyone looking for improved sound quality with advanced features beyond the traditional DAC.

The working principle of the AK4424ET is based on a sigma-delta topology. Its high-performance architecture is comprised of two main components: a decimator and a multi-bit delta-sigma modulator. The decimator performs the digital filtering process and reduces the digital signal’s bandwidth to the desired 16kHz-192kHz range, depending on the sampling rate. Next, the delta-sigma modulator uses a feedback loop to generate a multi-bit output from the digital signal. This output is then converted to an analog voltage level signal, allowing the DAC to produce an enhanced sound quality.

In addition to the digital filter and delta-sigma modulator, the AK4424ET also features several built-in features such as MP3, WMA, and AAC decoding, a low noise headphone amplifier, EMI filter control, and independent mute control. The product also includes a set of digital control registers for advanced audio processing and user interfaceaccess from the host system. The AK4424ET is embedded in a 40-pin LQFP package and is capable of operating at 2.5V to 3.3V, making it ideal for battery-powered audio systems.

In conclusion, the AK4424ET is a next-generation DAC that is designed to accommodate a wide range of audio applications. Its advanced signal processing and noise inhibition compatibility make it a reliable choice for anyone looking for improved sound quality with advanced features. Its wide range of features and intuitive user interface allow for a greater level of control over the audio output when used in various audio systems. With its great performance, the AK4424ET is a powerful solution for providing high-fidelity sound quality.
