Very High Performance Premium Sound Quality 32-bit 4-channel Audio DAC
Four digital filters are integrated into the AK4414: a short delay sharp roll-off filter and a short delay slow roll-off filter for minimum delay, and a sharp roll-off and a slow roll filter that have no phase difference.
The AK4414 supports DSD (Direct Stream Digital) or PCM data input. Since the AK4414 contains an integrated low-pass filter only for DSD data, the required performance in the SACD format book (Scarlet Book) can be easily realized with a simple external analog filter. The output level is the same for either PCM or DSD input data, as well as external digital filter input. Volume control is independent of the data input type.
The AK4414 is an upward compatible device from the AK4413, enabling an easy system upgrade. Supporting both PCM and DSD audio data, the AK4414 is ideal for high-end audio equipment, including high-end Blu-Ray, DVD-Audio, and SACD players, AV receivers and digital mixers. The device features fully differential outputs, digital attenuator, de-emphasis filter, soft mute circuit and zero detection. The sampling rate ranges from 30kHz to 216kHz, and the typical operating voltage is 5.0V for the analog block and 3.3V for the digital block.
Evaluation boards and samples are available now.
