Note: 1. Must not exceed the maximum rating of 6.0 V (namely, VD ≤ (VA+0.3 V) ≤ 6.0 V).
(VA is a power supply to supply silicon substrate potential.)
WARNING: Operation at or beyond these limits may result in permanent damage of the device.
Normal operations are not guaranteed under these critical conditions in principle.

Note: 1. Start up VA simultaneously with or earlier than VD, and stop VD simultaneously with or earlier than VA.
2. When starting and stopping the power supply, meet the absolute maximum rating condition: VD ≤ (VA+0.3 V).
It is generally recommended to use at VD ≤ VA. However, the VD must be 4.75 volts or more.
3. The analog input voltage and output voltage are proportional to the VRADH and VRDAH voltages.
