AK7756

DSP with Mono CODEC + Mic/Lineout Amp

GENERAL DESCRIPTION

The AK7756 is a highly integrated digital signal processor, including a mono voice audio codec, a MIC

pre-amplifier and digital audio I/F. The audio DSP has 9216step at fs = 8kHz parallel processing power.

As the AK7756 is a RAM based DSP, it is programmable for user requirements such as hands free and

acoustic effect. The AK7756EN is available in a space saving small 28pin QFN package and the

AK7756VF is available in a 30pin VSOP package.
