• Manufacturer Part Number: ak5365
• Description: 24-bit 96khz ?? Adc With Selector/pga/alc
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
Figure 24 shows the system connection diagram. An evaluation board is available which demonstrates application circuits,
the optimum layout, power supply arrangements and measurement results.
MS0164-E-01
Master Mode, 3-wire control (CTRL pin = “L”)
Note:
- AVSS and DVSS of the AK5365 should be distributed separately from the ground of external digital devices
- When LOUT/ROUT drives a capacitive load, resistors should be added in series between LOUT/ROUT
- All input pins except pull-down pin (ALC, SMUTE pins) should not be left floating.
