AK4429ET

An AK4429ET is an audio processing IC intended for use as part of a digital audio system. It is designed to provide high quality sound reproduction in a variety of application fields, ranging from portable audio playback to professional hi-fi systems. It features advanced 32/33-bit processing for improved sound quality, with a dedicated digital filter designed to eliminate unwanted noise and distortion.

The AK4429ET is particularly suitable for digital audio signal processing in audio systems such as AV amplifiers, car audio, home cinema receivers, and stereos. It can also be used in professional audio equipment such as mixing consoles and professional recording studios. It is also ideal for digital communication networks, such as broadcast, media, and IP networks.

The AK4429ET has a variety of features that make it useful for a range of applications. It has an internal programmable gain control (PGC) that can be used to adjust and control the output level, allowing for optimal sound reproduction. PGC also ensures that the device has uniform sound staging across multiple loudspeakers, regardless of the distance between them.

The AK4429ET also has an integrated linear-in-phase regulator that provides step-less gain accuracy and low noise floor in its analog output, allowing for improved sound quality and consistent sound reproduction. It also features a low-dispersion digital filter designed to reduce unwanted harmonic characteristics. This filter is especially effective at eliminating cross-correlation between channels in a two-channel system.

The working principle of the AK4429ET is based on inter-sample peak control (ISP) technology. This technology analyses the audio signal on a frame-by-frame basis and adjusts the gain control as necessary in order to reduce distortion and optimize sound performance. This ensures that the gain control is consistently applied across the entire signal, resulting in consistent sound quality.

In summary, the AK4429ET is an audio processing IC designed for a range of application fields, including portable audio playback, AV amplifiers, car audio systems, professional audio equipment, and digital communication networks. It has a range of features, such as an integrated linear-in-phase regulator, a programmable gain control, and a low-dispersion digital filter, which make it useful for a variety of applications. The working principle of the device is based on inter-sample peak control technology, which ensures uniform sound quality by consistently applying gain control to the audio signal.
