LT1039A/LT1039A-16
ELECTRICAL CHARACTERISTICS
The q denotes specifications which apply over the full operating
temperature range.
Note 1: VON/OFF = 5V for LT1039AM grade devices.
Note 2: VON/OFF = 0.4V for – 55°C ≤ TA ≤ 100°C and VON/OFF = 0.2V for
100
°C ≤ TA ≤ 125°C. Does not apply to LT1039A-16 part.
Note 3: For TA ≥ 100°C leakage current is 350µA max.
Note 4: Bias pin open on 18-pin version.
