Note 1. All voltages with respect to ground.
Note 6. The power up sequence between AVDD, DVDD, SVDD and VVDD is not critical. The internal circuit is invalid
when power up the AK4636 at the PDN pin = “H”. Set the PDN pin to “L” to reset the internal circuit after
power up. To avoid an internal circuit error, the PDN pin must be “L” upon power up, and changed to “H” after
all power supplies are supplied. The AK4636 can not be partially powered-off, all powers must be ON.
(Power-off state is identified as when the power supplies are floating or short to ground.) When connecting the
AK4636 to the I2C bus, do not turn the AK4636 off unless other external devices are off.
* AKM assumes no responsibility for the usage beyond the conditions in this datasheet.
