Test Conditions/Comments
Digital inputs = VIL or VIH
Digital inputs = 0 or 5 V
Notes:
1
Full Scale Range (FSR) is 10V for unipolar mode.
2
Guaranteed but not production tested.
3
See timing diagram (Figure 2.).

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. All inputs have protection diodes which will protect the device from short
transients outside the supplies of less than 100mA for less than 100 ms.
