The glitch impulse transferred to the output of one converter (not adjusted) due to a change in the digital input code to another
addressed converter.

NOTES:

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.
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 diodeswhich will protect the device from short
transients outside the supplies of less than 100mA for less than 100
μ
s.
