A member of the Audio4Pro product family, the 32-bit stereo D/A converter has three different digital filters: a 32-bit short-delay filter. which is suitable for acoustic sounds, a 32-bit sharp roll-off filter for traditional sounds, and a 32-bit slow-rolloff filter for a soft sound expression. These features enable the device to offer higher-quality sound for professional and high-end digital musical instruments.

Sampling rates range from 30 to 216 kHz. The analog outputs are fully differential, achieving a THD+N of 100 dB and dynamic range or SNR of 114 dB, and the operating voltage is 5 V. The AK4480 integrates a digital de-emphasis filter, soft mute circuit, digital attenuator, and supports 216-kHz PCM audio data. (Call company for pricing samples now.)
