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.
