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.
