Asahi Kasei Microdevices Corporation (AKM) has redesigned the AK4490 D/A converter (DAC) and its higher-end counterpart, AK4493, as new products under the VELVET SOUND brand.
These new devices, AK4490R and AK4493S, use advanced VELVET SOUND technology to improve electrical margin and stability. They achieve an unprecedented level of audio integrity and dynamics while maintaining the reduced power consumption of the original AK4490 and AK4493.
The AK4490R and AK4493S accept up to 768 kHz PCM data and 22.4 MHz DSD data (AK4493S). They accurately reproduce the information-rich, unaltered audio data of high-resolution sound sources.
Samples start shipping in February 2022. AKM expects both devices to be available in volume production in the second quarter of 2022.
Advanced VELVET SOUND technology for high-quality sound
The AK4493S and AK4490R have been redesigned to optimize signal path impedance for much-improved noise immunity, particularly as it applies to low-frequency noise performance. These new products achieve a dynamic and responsive sound while reducing unnecessary power consumption.
High performance analog characteristics
AK4493S: DR, S/N 123dB (2Vrms), 128dB (Large Amplitude Mono mode) THD+N: -115dB
AK4490R: DR, S/N 120dB (2Vrms), 123dB (Mono mode) THD+N: -112dB
Supports high-resolution sound sources
These devices accept up to 768 kHz PCM data and 22.4 MHz DSD data (AK4493S).
