6. Peripheral I/F Example
The AK4627 supports signals from external devices which are operated on 3.3V power supplies for TTL inputs. The
power supply for output buffer (TVDD) should be 3.3V when those external devices are connected. Figure 35 shows an
I/F example when 3.3V and 5V power supply devices are used.
