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.
