Notes
* 3. All voltages are with respect to ground. AVSS and DVSS1-3 must be connected to the same ground.
* 4. The maximum analog input voltage is smaller value between (AVDD+0.3)V and 4.3V.
* 5. The maximum digital input voltage of SDIN1, SDIN2/JX0, LRCK1, BICK1, LRCK2/JX1, BICK2/JX2,
PDN, SCLK/SCL, CSN and SI/I2CFIL pins is smaller value between (TVDD+0.3)V and 4.3V.
* 6 . The maximum digital input voltage of SDIN3/JX3, SDIN4, LRCK3, BICK3, TESTI and XTI pins is
smaller value between (VDD33+0.3)V and 4.3V.
WARNING: Operation at or beyond these limits may result in permanent damage to the device. Normal
operation is not guaranteed at these extremes.

Notes
* 7. The power-up sequence with AVDD, DVDD, TVDD and VDD33 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.
* 8. Do not turn off the power supply of the AK7735 with the power supply of the peripheral device turned
on. When using the I²C interface, pull-up resistors of SDA and SCL pins should be connected to
TVDD or less voltage.
WARNING: AKM assumes no responsibility for the usage beyond the conditions in the datasheet.
