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: V_ON/OFF = 5V for LT1039AM grade devices.
Note 3: V_ON/OFF = 0.4V for –55°C ≤ T_A ≤ 100°C and V_ON/OFF = 0.2V for
100°C ≤ T_A ≤ 125°C. Does not apply to LT1039A-16 part.
Note 4: For T_A ≥ 100°C leakage current is 350µA max.
Note 5: Bias pin open on 18-pin version.
