Description

Asahi Kasei Microdevices Corporation (AKM) has released the AK4468VN, a premium multi-channel audio D/A converter. This device is the successor to the AK4458VN, which has proven successful in both the consumer and automotive audio space. The AK4468VN is the latest product of AKM’s VELVET SOUND LSI manufacturing process, which was developed specifically for premium audio devices such as the flagship DAC, AK4499.

Features

● AKM’s premium audio LSI manufacturing process

AKM’s audio-optimized LSI manufacturing process allows for the implementation of very low-impedance signal paths. This process results in much-improved noise immunity in general, and increased low-frequency noise performance in particular. As a result of these factors, the AK4468VN’s sound quality surpasses that of its predecessor, the multi-channel DAC AK4458VN. The AK4468VN is pin- and register-compatible with the AK4458VN.


● Supports AEC-Q100

The AK4468VN guarantees an operating temperature up to 105°C, and will comply with AEC-Q100 requirements.


● VELVET SOUND technology

As an AKM premium audio product, the AK4468VN supports VELVET SOUND features such as low-distortion technology and OSRD (Over Sampling Ratio Doubler) technology, which improve out-of-band noise suppression.
