AK7600VF Evaluation Board Rev.1
GENERAL DESCRIPTION
The AKD7600-A is an evaluation board for AK7600VF, which is a highly integrated audio processor
including a stereo ADC, three stereo DAC and digital functions (equalizers, digital filters, delay memories,
etc.). AK7600VF needs 5V power supply. The regulators on the AKD7600-A board supply regulated 5V to
the device and AK7600VF can be also supplied directly 5V without a regulator. This board is composed of
a main board and a sub-board. It is possible to control the setting of the board via an USB port. RCA
connectors are used for inputs and outputs of analog signals. This board also has a digital interface and
can achieve the interface with a digital audio system through an optical connector.
