note 1: All the value mean the voltage against the ground pin.
2: Maximum absolute value must be within 6.0V, i.e. VB+0.3V ≤ 6.0V.
Warning: To operate beyond these limits may result in permanent damage to the device.
Normal operation is not guaranteed at these extremes.

note 1: All the value mean the voltage against the ground pin.
2: The VA and VB should be powered at the same time or earlier than VD.
3: The VA and VB are connected together through the chip substrate and has several ohms resistors.
The VA and VB should be supplied from the same power unit.
4: Analog input/output voltages are proportional to the voltages of VRADH,VRDAH.
