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.

WARNING: Operating at or beyond these limits may result in permanent damage to the device. Normal operation is

not guaranteed at these critical conditions.

WARNING: AKEMD assumes no responsibility for the usage beyond the conditions in the datasheet.

Note) Do not turn off the power of the AK7742 during the power supplies of surrounding devices are turned on. VDD

must not exceed the pull-up of SDA and SCL of I2C BUS. (The diode exists for DVDD in the SDA and SCL pins.)
