Next Generation Premium Multi-Channel DAC Series from AKM Reaches the Market

The new series of 2/4/6/8ch D/A converters from Asahi Kasei Microdevices (AKM) is powering a new generation of high-quality consumer electronic devices, measurement equipment and control systems, now reaching the market. 
 
The AK4452/AK4454/AK4456/AK4458 is a new generation of premium 32-bit DAC devices, with up to 8-channels, based on AKM’s Velvet Sound architecture and now adopted by well-established high-end audio companies. Combining fine sound details with its low-distortion architecture in addition to 32-bit resolution digital filter processing, the new technology from AKM is already finding applications in new-generation AV Receivers, Network Audio and USB DACs, USB Headphones, Audio Interfaces, Car Audio and Measurement Equipment and Control Systems with high-resolution audio support.
 

The digital input in this new AKM premium multi-channel DAC series supports up to 768 kHz PCM and 11.2 MHz DSD (Direct Stream Digital), suitable for high-resolution audio source playback. With up to 8-channel and a TDM interface allowing daisy chaining, the series also provides a simple solution to a wide range of applications.
 
According to AKM, its Velvet Sound core architecture was designed specifically to support the high-resolution audio market and achieves the lowest distortion in the industry with -107dB in the D/A conversion and 115dB S/N. Using OSRD (Over Sampling Ratio Doubler), the new chips reduce out of band noise and include IRD (Impulse Response Designed) filters, integrated with 32-bit processing. Five different digital filters types are selectable according to the user audio and system preferences.
 
Available in 32-pin QFN, 5x5 mm (AK4452/AK4454) and 48-pin QFN, 7x7 mm (AK4456/AK4458) packages, the new-generation AKM 2ch/4ch/6ch/8ch lineup is able to support a variety of designs, including multichannel playback system such as AV surround receivers and audio interfaces.
