Four digital filters are integrated into the AK4413: 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. With the short delay slow roll-off option, group delay is just 5.5/fs (for any fs), ideal for live sound applications.
The AK4413 delivers high performance with a very short group delay, making it ideal for pro audio applications, including live sound. A performance boosting mode is available, where the AK4413 is configured as a stereo device, which increases dynamic range to 123dB. 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.
