[AK7770] AK7770EQ Audio DSP with Multi-Channel Audio CODEC GENERAL DESCRIPTION The AK7770 is a digital signal processor with an integrated 4-channel audio ADC and a 6-channel audio DAC, as well as an S/PDIF transmitter.
It utilizes an enhanced dual bit architecture that results in wide dynamic range for the ADC, and the advanced multi-bit architecture of the DAC enables wide dynamic range and low out-of-band noise.
Two sample-rate converters are integrated, allowing for operation at 48kHz sampling rate with input rates of 32kHz, 44.
1kHz, or 48kHz.
Volume control, compression, EQ and sound processing are performed by the DSP.
In addition, delay adjustment up to 70ms is possible for four outpu...
