AK4528VM is an audio CODEC that consists of 8 stereo and 8 mono audio channels and supports 24-bit/96kHz audio with low power consumption. The AK4528VM is a high preceptual audio CODEC designed to process audio signals at high speeds while maintaining high sound quality. It supports a wide range of audio codecs, including MP3, WMA, AAC and OGG.

Application field

The application field of the AK4528VM is wide, including digital audio playback and recording, mobile applications, set-top boxes, DVRs, televisions, automotive audio and digital home entertainment systems, among others.

In digital audio playback and recording, the AK4528VM supports multiple digital audio formats and can work as both a digital-to-analog converter (DAC) and an analog-to-digital converter (ADC). This allows for high fidelity audio playback and recording. In mobile applications, such as smartphones and tablets, the AK4528VM can be used as a headphone amplifier and speaker driver, as well as a microphone input.

The AK4528VM can be used as a component of set-top boxes and DVRs. It allows for high quality audio decoding and encoding, as well as routing of audio signals between different components in the device. In television applications, the AK4528VM can be used as a component in the audio receiver of a television set.

In automotive audio applications, the AK4528VM can be used as a component in the audio receiver of a car radio. It supports high quality audio playback with low power consumption and no interference. Furthermore, the AK4528VM can also be used as part of digital home entertainment systems, such as soundbars, to decode and encode audio signals.

Working Principle

The working principle of the AK4528VM is based on analog-to-digital and digital-to-analog conversion, as well as the processing of audio signals. The AK4528VM is equipped with on-chip high-fidelity headphone amplifiers and built-in pulse-width modulation (PWM) PCM and DACs. The high-fidelity amplifiers support a wide range of audio codecs and allowing for low power consumption regardless of audio format. The integrated ADC can be used for analog-to-digital conversion of audio signals, which is then routed through the AK4528VM for further processing.

The AK4528VM has dedicated channel control, digital mixing and volume control blocks. The dedicated channel control block allows for the routing of audio signals between the input and output channels. The digital mixing block allows for the mixing of multiple input channels into a single output channel, as well as for setting the levels of each channel individually. The volume control block supports digital, soft-mute and mono/stereo modes. Furthermore, the AK4528VM supports I2S and I2C communication.

In summary, the AK4528VM is a high quality audio CODEC designed for a wide range of applications, such as digital audio playback and recording, automotive audio, and digital home entertainment systems. It supports multiple audio codecs, as well as features such as dedicated channel control, digital mixing and volume control. The AK4528VM works based on analog-to-digital and digital-to-analog conversion, as well as routing and processing of audio signals. It also supports I2S and I2C communication.
