Description

The AK7716 is a highly integrated audio processing IC, including 4 24-bit output D/A channels, a stereo 20-bit input A/D, on-chip DSP. High quality analog performance is provided by quad D/A with 113dB dynamic range, and stereo A/D with 98dB dynamic range. These converters support the standard audio sampling frequencies of 48,44.1 and 32kHz.

The programmable DSP is optimized for audio signal processing. The design allows up to 512 execution lines per audio sample cycle, with multiple functions per line. The AK7716 has a self-boot capability, using an external EEPROM.

The AK7716 can be used to implement complete sound field control, such as echo, 3D, parametric equalization,etc. It is packaged in a 100-lead LQFP package
