Test Conditions/Comments
All digital inputs = 0 V or all = 5 V
NOTES:
1 Full Scale Range (FSR) is 10V for unipolar mode.
2 Guaranteed but not production tested.
3 Digital input levels should not go below ground or exceed the positive supply voltage, otherwise damage may occur.
4 See timing diagrams.
5 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.
