Premium ADCs AK557X
VELVET SOUND VERITA The AK557x series is a 32-bit, 768 kHz sampling, differential input A/D converter for digital audio systems. It achieves 121 dB dynamic range and 112 dB S/(N+D) while maintaining low power consumption performance. The AK5572 integrates a 2-channel A/D converter, suitable for mixers and multi-channel recorders. Four types of digital filters are integrated and selectable according to the sound quality preference. The AK5572 can be easily connected to a DSP by supporting TDM audio formats. Additionally, it supports DSD output up to 11.2MHz.The channel summation mode improves the dynamic range performance by summing-up multiple channel A/D data and averaging. The dynamic range is improved to 124 dB in 2-to-1 mode.
●Maximum Sampling Frequency/Resolution: PCM768kHz/32-bit, DSD256(11.2MHz)/1-bit
●SNR: 121dB
●THD+N: -112dB
●Sound Color Digital Filter: 4 types
