Note 11. AVDD, LVDD, TVDD1 and TVDD2 must be powered up first before DVDD when DVDD is
supplied externally (LDOE pin = “L”). In this case, the power-up sequence with AVDD, LVDD,
TVDD1 and TVDD2 is not critical. The PDN pin should be held “L” when power is supplied. The
PDN pin is allowed to be “H” after all power supplies are applied and settled.
Note 12. When using the I²C interface, (I2CSEL pin = “H”), do not turn off the power supply of the
AK7758 with the power supply of the surrounding device turned on. Pull-up of SDA and SCL
pins must not exceed TVDD2.
WARNING: AKM assumes no responsibility for the usage beyond the conditions in the datasheet.
