Note 1. The maximum junction temperature of the NTE1509 is +100°C. Device must be derated for
operation at elevated temperatures. Junction to ambient thermal resistance is 55°C/W.
Note 2. Pin5 input current must be limited to ±3mA. The addition of a 39kΩ resistor in series with
Pin5 allows ±100V signals without damage.

Note 2. Pin5 input current must be limited to ±3mA. The addition of a 39kΩ resistor in series with
Pin5 allows ±100V signals without damage.
Note 3. Accuracy is measured referred to +10.000VDC at Pin5, with + 10.000VDC at Pin6, and
0.000VDC at Pin4. At lower full–scale voltages, buffer and comparator offset voltage may
add significant error. See table for threshold voltages.
