AK4120
Sample Rate Converter with Mixer and Volume
GENERAL DESCRIPTION
The AK4120 is a stereo asynchronous sample rate converter. The input sample rate range is from 8kHz
to 48kHz. The output sample rate is fixed at 32kHz, 44.1kHz, 48kHz or 96kHz. AK4120 includes a
digital mixer and digital volume control. Applications for this device include pro audio mastering,
consumer format conversion and desktop audio production and playback.
