MP3 Audio Decoder IC
PT8402B
DESCRIPTION
The PT8402B is a single chip MPEG audio decoder capable of decoding all layers compressed
elementary streams, as specified in MPEG 1 and MPEG 2 ISO standards, including the so called MP3.
In additional to decoding function, this chip also include a high-performance D/A converter and
headphone driver, so user can eliminate the need of external DAC and output circuit.
With external A/D converter, it can also compress incoming signal by using ADPCM algorithm,
therefore it can also playback ADPCM bitstream.
FEATURES
