Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. This device contains latch−up protection and exceeds 100 mA per JEDEC Standard JESD78.

3. See characterization table for linearity over negative bias voltage – we recommend keeping the level on pin 3 below −300 mV.
4. A 1−MW resistor is connected from pin 4 to the ground for the measurement.
