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 100µs.
3 _{GND refers to AGND and DGND.}
