Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: TA > 85°C, I bias maximum is 100nA.
Note 3: For TA ≤ – 40°C output current sink drops to 2.5mA.
