Note 3. All voltages are with respect to ground. AVSS and DVSS1-3 must be connected to the same ground.
Note 4. The maximum analog input voltage is smaller value between (AVDD+0.3)V and 4.3V.
Note 5. The maximum digital input voltage of SDIN1, SDIN2/JX0, LRCK1, BICK1, LRCK2 and BICK2
pins is smaller value between (TVDD1+0.3)V and 4.3V.
Note 6. The maximum digital input voltage of SDIN3/JX1, SDIN4, LRCK3/JX2, BICK3/JX3, LRCK4,
BICK4, PDN, SCLK/SCL, SO/SDA, CSN and SI/I2CFIL pins is smaller value between
(TVDD2+0.3)V and 4.3V.
Note 7. The maximum digital input voltage of SDIN5/JX0, SDIN6, LRCK5, BICK5, 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.

Note 8. The power-up sequence with AVDD, DVDD, TVDD1, TVDD2 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.
Note 9. Do not turn off the power supply of the AK7738 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 TVDD2 or less voltage.
WARNING: AKM assumes no responsibility for the usage beyond the conditions in the datasheet.
