The AK4490EQ is a high performance portable audio DAC device and it is one of the world’s most advanced D/A converters with 192kHz sampling rate and 22bit dynamic range, for use in a wide range of audio applications including home audio, car audio, portable audio, professional audio and more.

The AK4490EQ is designed to provide a powerful yet flexible platform for developing digital audio solutions in both consumer and professional audio applications. It has very low current consumption and high efficiency design, making it an ideal choice for use in mobile or portable audio applications. The AK4490EQ also integrates four-channel digital volume control and noise shaping technology, allowing for precise control over digital audio playback without the need for external digital-to-analog converters.

The AK4490EQ features low-noise, low-distortion, high-dynamic-range Digital-to-analog (DAC) technology, which makes it well-suited to a variety of different types of applications in both consumer and professional audio products. With its high-resolution audio support and advanced processing algorithms, the AK4490EQ provides an ideal solution for a variety of music playback applications, including professional studio monitoring, custom home theater systems, portable audio devices, and other audio systems.

The AK4490EQ’s working principle is based on Digital-to-Analog (DAC) conversion, meaning it converts digital data into an analog signal. In the case of the AK4490EQ, it converts digital audio information from a PCM or DSD source into an analog electrical signal that is then amplified and sent to a speaker or headphones. This analog signal is created by the D/A converter using mathematical algorithms to create a digital version of the analog waveform that it represents. The AK4490EQ’s DAC is capable of producing up to a 192kHz sampling rate, which is capable of providing high-resolution audio reproduction.

The AK4490EQ offers a variety of features that make it suitable for use in a wide variety of audio applications. For example, it features low output distortion, low noise, low jitter, and adjustable gain. Additionally, it has integrated low-noise Dynamic Element Matching (DEM) technology, which provides precise matching of the DAC’s output impedance to the audio source’s impedance. This allows for accurate and reliable audio playback. The AK4490EQ also features built-in noise shaping technology, which is used to reduce noise and distortion in the output signal.

The AK4490EQ is suitable for use in a wide variety of audio applications, from portable audio devices to multi-channel audio production in professional studio environments. It is also ideal for use in car audio systems, home theater systems, and many other audio applications that require high-resolution audio processing. The AK4490EQ is an excellent choice for those looking for a powerful yet efficient D/A converter for their audio application.
