AK7758

DSP with Stereo CODEC + Mic/Lineout Amp

1. General Description

The AK7758 is a highly integrated digital signal processor, a stereo audio CODEC, a MIC pre-amplifier, a

line-out amplifier, digital audio I/F. The main and sub DSPs have 3072step at fs = 48kHz parallel

processing power. As the AK7758 is a RAM based DSP, it is programmable for user requirements such

as high performance hands free function and acoustic effects. The AK7758 is available in a space saving

small 36-pin QFN package.

2. Features
