• Manufacturer Part Number: ak4524
• Description: 24bit 96khz Audio Codec
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
Figure 10 & Figure 11 show the system connection diagram. This is an example which the AK4524 operates at X’tal
mode. In case of external clock mode, please refer to Figure 11. An evaluation board (AKD4524) is available which
demonstrates application circuits, the optimum layout, power supply arrangements and measurement results.

Controller
- X’tal Oscillation circuit is specified from 11.2896MHz to 24.576MHz.
- AGND and DGND of AK4524 should be distributed separately from the ground of external controller etc.
- When AOUT+/− drives some capacitive load, some resistor should be added in series between AOUT+/− and
- All input pins except pull-down pin (TEST) should not be left floating.
