GENERAL DESCRIPTION
AKD4671 is an evaluation board for the AK4671, stereo CODEC with built-in Microphone-Amplifier,
Receiver-Amplifier and Headphone-Amplifier.
The AKD4671 can evaluate A/D converter and D/A converter separately in addition to loopback mode
(A/D
→ D/A). The AKD4671-B also has the digital audio interface and can achieve the interface with
digital audio systems via opt-connector.
