GENERAL DESCRIPTION
The AK4353 is a stereo CMOS D/A Converter and Digital Audio Interface Transmitter. The DAC signal
outputs are single-ended and are analog filtered to remove out of band noise. Therefore no external filters
are required. The AK4353 can operate at the power supply from 2.7V to 5.5V and the digital I/F can
correspond to both TTL and CMOS levels.
