AKD7742规格书详情
GENERAL DESCRIPTION
The AK7742 is a highly integrated audio digital processor, including two stereo 24bit DAC’s and one stereo ADC with input selector. The stereo DAC and ADC feature high performance, archiving 106dB and 96dB dynamic range respectively, 8kHz to 96kHz sampling rate are supported. The audio DSP has 1536step/fs parallel processing power, and 74k-bit delay memory allows surround processing, acoustic effect and parametric equalizers. Asthe AK7742 is a RAM based DSP, it is programmable for user requirements. The AK7742 is available in a space saving small 48pin LQFP package.
