AK7730A

24bit 2ch ADC+ Audio DSP

1. General Description

The AK7730A is a highly integrated audio processing IC, including a stereo 24-bit input A/D and on-chip

DSP. High quality analog performance is provided by a stereo A/D with 97dB (48 kHz) dynamic range. This A/D

supports sampling frequencies from 8 kHz to 96 kHz. This device includes 72kbit SRAM for delayed audio data

that is suitable for simulated surround like a hall simulation. This programmable DSP part supports the sampling

frequencies from 8 kHz to 192 kHz. The design allows up to 4608 execution lines per audio sample cycle at 8 kHz,

768 at 48 kHz, 192 lines at 192 kHz with multiple functions per line. The AK7730A can be used to implement

complete sound field control, such as echo, 3D, parametric equalization, etc. It is packaged in a 48-lead LQFP

package.
