Note 3. The TVDD pin is the power supply pin for pin number 1 ~ 8 pins.
Note 4. The power-up sequence with VDD and TVDD 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 5. Do not turn off the power supply of the AK7736B with the power supply of the surrounding device
turned on. VDD must not exceed the pull-up of SDA and SCL of I2C BUS. (The diode exists for
VDD in the SDA and SCL pins.)
