(VSS1=VSS2=0V:
Note 1. All indicated voltages are with respect to ground. VSS1 and VSS2 must be the same voltage.
Note 2. The maximum value of analog input voltage is smaller value between (AVDD+0.3)V and 4.3V.
Note 3. The maximum value of digital input voltage is smaller value between (DVDD+ 0.3)V and 4.3V.
(VSS1=VSS2=0V:
Note) Do not turn off the power of the AK7742 during the power supplies of surrounding devices are turned on. VDD
