AK7780

[AK7780] AK7780 24bit 5ch ADC & SRC + Audio DSP GENERAL DESCRIPTION The AK7780 is a highly integrated audio processor, including a 28-bit floating point DSP, two 24-bit stereo ADC’s and one mono ADC. The stereo ADC’s feature high performance, achieving 96dB dynamic range, they include 8:1 input selectors. The ADC supports sampling frequencies from 7.35 kHz to 96 kHz. The AK7780 also includes a stereo sample rate converter (SRC), so it can be used as a master device when it receives digital audio inputs. The DSP includes 168kbits of SRAM for audio delay data that is suitable for creating simulated surround fields. The programmable DSP block is realized with 2560step/fs DSP. It supports sampling frequencies from 7.35kHz to 96 kHz. The AK7780 is used to implement complete sound field control, such as echo, 3D, parametric equalization, and other sound enhancements. It is packaged in a 100-lead LQFP package. FEATURES [DSP] Main „ Word length: 28-bit (Data RAM F24.4 limited range floati...
