Asahi Kasei Microdevices Corporation, (AKM), has developed a new D/A converter, (DAC), the AK4499EQ. It is the latest, “VELVET SOUND|VERITA”, product, following the prior generation flagship DAC, the AK4497EQ. The AK4499 adopts Current Output architecture, which is the first among AKM products. It achieves the world’s highest class of low THD+N and high S/N. Samples will be available in January, 2019, and Mass Production starts from May, 2019.
Come see us at the AKM audio room at CES2019 and be one of the first to listen to this this new revolutionary DAC. (Reservation required. Inquire with your Business Development Manager to arrange an appointment.)
THD+N: -124dB can be achieved from the Low Distortion Technology optimized for Current Output architecture. 140dB DR and S/N are also achieved in mono mode.
The same Dedicated for Premium Audio LSI process and Premium Audio Non-Magnetic Packaging Technology as the AK4497EQ developed for audio by AKM is also used for the AK4499EQ. It can improve electrical margin and noise around low frequency ranges dramatically.
