2/6-Channel Audio CODEC with Digital EQ

GENERAL DESCRIPTION

AK7600 is a CODEC (2ch ADC, 6ch DAC) with a delay line memory and digital filters such as EQ. This

device operates in master mode and the internal sampling rate is 44.1kHz. It supports 5.0V single input

and the integrated regulator generates the internal voltage. The 2-channeled ADC achieves dynamic

rage of 97dB single end inputs, and 6-channeled DAC achieves 102dB single end outputs. The delay line

memory covers 36ms in total. Time alignment of 6m or less is possible since the delay line memory can

store for 18ms data for both left and right channels. A car audio system can be built easily 5-bands EQ

and time alignment functions.
