The AK7714 is a highly integrated audio processing IC with 20-bit stereo ADC and 4-channel DAC plus on-chip DSP with 64-kbit delay RAM. The built-in ADC has a dynamic range of 99 dB with S/(N+D) of 92 dB, and the DAC has a dynamic range of 98 dB with S/(N+D) of 89 dB, thereby ensuring high performances. The AK7714 is compatible with each of the sampling frequencies of 48 kHz, 44.1 kHz or 32 kHz, and a program of 512 steps (when sampling at 44.1 kHz or 32 kHz) can be executed in one sampling time. The AK7714 is a programmable audio DSP containing RAM for delay. This allows sound field control programs to be implemented for surround sound, echo 3D, parametric equalizer and the like. Furthermore, the AK7714 uses a small 100-pin LQFP package, providing the optimum system for the sound field of car audio equipment which is required to meet space saving requirements.
