SYSTEM DESIGN
Figure 38 shows the system connection diagram. An evaluation board [AKD4370] is available which demonstrates the
optimum layout, power supply arrangements and measurement results.

Notes:
- VSS1 and VSS2 of the AK4370 should be distributed separately from the ground of external controllers.
- All digital input pins (I2C, SDA/CDTI, SCL/CCLK, CAD0/CSN, SDATA, LRCK, BICK, MCKI, PDN) must
not be left floating.
- When the AK4370 is used in master mode, LRCK and BICK pins are floating before the M/S bit is changed to
“1”. Therefore, a 100k
Ω
pull-up resistor should be connected to the LRCK and BICK pins of the AK4370.
- When DVDD is supplied from AVDD via 10
Ω
series resistor, the capacitor larger than 0.1
μ
F should not be
connected between DVDD and the ground.
