Figure 45. Typical Connection Diagram
Notes:
- AVSS, DVSS and SVSS of the AK4632 should be distributed separately from the ground of external
controllers.
- The exposed pad on the bottom surface of the package must be open.
- All digital input pins except pull-down pin should not be left floating.
- Value of R and C of BEEP pin should depend on system.
- When the AK4632 is EXT mode (PMPLL bit =
“
0
”
), a resistor and capacitor of VCOC pin is not needed.
- When the AK4632 is PLL mode (PMPLL bit =
“
1
”
), a resistor and capacitor of VCOC pin is shown in Table 45.
- Input resistance of AIN pin and Capacitance between MICOUT pin and AIN pin compose of HPF. When the
capacitance is 0.22
μ
F, the cut off frequency is typ.72Hz(typ)(min. 48Hz, max. 145Hz).
