[Description]
Asahi Kasei Microdevices Corporation (AKM) is a leading supplier of high performance audio A/D converters (ADCs) for more than 25 years since AKM had released a delta-sigma ADC as the first generation in 1988. AKM has always been focusing on not only high performance but also low power consumption characteristics, releasing the AK5394A: a 24-bit advanced multi bit architecture ADC as the second generation in 2002, and the AK5397: a world-class S/N 127dB flagship premium 32-bit ADC in 2014. Recently, the high-end audio market is being driven by the growing availability of high-resolution sound sources. AKM has responded to this market demand and has launched a new 3rd generation premium high-end multichannel ADC VERITA AK557X series.

The AK557X captures incredible detailed and the true sound expression with its high resolution 32-bit processing by AKMs proprietary VELVET SOUND architecture that has been widely adopted by well-established high-end audio companies. This high resolution processing and noise tolerance designs of the AK557X realize a low distortion recording. Digital output supports unsurpassed high resolution sound, up to 768 kHz PCM and 11.2 MHz DSD output is available for the first time as an ADC.

This 2/4/6/8-channel line-up provides simple and optimal solution to any multichannel system by adopting the flexible TDM (Time Division Multiplexing) interface.

● Dynamic sound recording with large amount of information

- AKMs VELVET SOUND architecture is utilized Low-distortion technology achieves industry’s best performance of -112dB as an ADC with 121dB S/N characteristic.
- Channel summation improves the dynamic range up to 130dB S/N. (AK5578EN：8-to-1 mode)
- Four different IRD (Impulse Response Designed) digital filters types are selectable.

● Supporting High Resolution Data
- The digital output supports up to 768 kHz PCM and 11.2 MHz DSD (Direct Stream Digital), recording high-resolution sound that is as close as possible to the original acoustic source.
- It is suitable for high-resolution sound source recording that is becoming popular with Network Audio and USB DACs.

● System Extensibility
- 2ch/4ch/6ch/8ch lineups provide best sound solution for the system.
- The digital input supports TDM, realizing daisy chain connection. A multi-channel system such as multichannel recorders and mixers can be easily designed with these premium ADCs.
