AK2300
3.3V Single channel PCM CODEC LSI
GENERAL DESCRIPTION
The AK2300 is a single channel PCM CODEC for
various applications for example, AFE. It includes the
selectable linear PCM interface, A/m-law function,
mute and power down. All of these functions are
controlled by the pin.
It includes Band limiting filter, A/D and D/A converter,
and A-law/m-law converter. All functions are provided
in very small QFN(16pins) package and it is good for
reducing the mounting space.
