Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 2:
All currents into pins are positive and all voltages are referenced to may cause permanent damage to the device. Exposure to any Absolute GND unless otherwise indicated. Maximum Rating condition for extended periods may affect device
Note 3:
Guaranteed by design and not tested. reliability and lifetime. 4316fa For more information www.linear.com/LTC4316 3
