[AK7756] 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. FEATURES † DSP - Word length: 24bit (Data RAM 24bit floating point) - Instruction cycle: 13.
