Evaluation board Rev.A for AK4702
GENERAL DESCRIPTION
AKD4702 is an evaluation board for quickly evaluating the AK4702 , 2ch DAC with AV SCART switch.
Evaluation requires a audio/video analog analyzer, an analog video signal source, a digital audio signal
source, and a power supply. AKM’s ADC evaluation board can be also used for the audio source. Also
included is a AK4112B digital audio interface receiver which receives SPDIF compatible audio data. The
digital audio data is available via optical connector or BNC.
