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.
