Note 3. The power supply sequence for AVDD and DVDD is not critical but all power supplies must be On before start

operating the AK7734.

Note 4. Do not turn off the power supply of the AK7734 with the power supply of the surrounding device turned on.

DVDD must not exceed the pull-up of SDA and SCL of I2C BUS. (The diode exists for DVDD in the SDA and

SCL pins.)

WARNING: AKM assumes no responsibility for the usage beyond the conditions in the datasheet.
