AK4499 Datasheet | Asahi Kasei Microdevices

Description The AK4499 is a 32-bit 4ch Switched Resistor DAC which adopts newly developed technology, achieving the industry’s leading level low distortion and low noise characteristics. It corresponds to a 768k Hz PCM input and an DSD512 input at maximum, suitable for playback of high resolution audio sources that are being widespread in Network Audio and USB-DACs Audio systems. In addition, it is capable of supporting a wide range of signals and achieving low out-of-band noise. The AK4499 has six types of 32-bit digital filters, realizing simple and flexible sound reproduction in wide range of applications. 2.
