Full Scale Range (FSR) is 10V for unipolar mode.
Guaranteed but not production tested.
Digital input levels should not go below ground or exceed the positive supply voltage, otherwise damage may occur.
See timing diagram.
Specified values guarantee functionality. Refer to other parameters for accuracy.

NOTES:
1
Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
2
Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps
(HP5082-2835) from input pin to the supplies.
3
GND refers to AGND and DGND.
