Parallel Output Circuit, INT Output Circuit, SDA Output Circuit
Q0-4 bits setting are output from Q0-4 pins. Each output is open drain. Normally connected to DVSS with a 10kohm
resistance. INT pin is the same output circuit (Refer Figure 16).
SDA pin is open drain output, and connected to DVSS with a resistance. Refer to I
2
C bus standard as for resistance value.
As there is a protection between each pin and DVDD, the pulled-up voltage should be DVDD or lower. And if the
pulled-up voltage is supplied from the different power supply from DVDD, only DVDD should not be powered off
independently. When PDN pin =“L” and DVDD is supplied to the AK4220, the AK4220 can be in power-down state. In
Power-down state, VVDD1-2 and AVDD can be powered off.
