Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is func-
tional, but do not guarantee specific performance limits. Electrical Characteristics state DC andAC electrical specifications under particular test conditions which guar-
antee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit is
given, however, the typical value is a good indication of device performance.

Note 3:
Accuracy is measured referred to +3 dB = +10.000 V
at pin 5, with +10.000 V
DC
at pin 6, and 0.000 V
DC
at pin 4. At lower full-scale voltages, buffer and
comparator offset voltage may add significant error. See table for threshold voltages.
Note 4:
Pin 5 input current must be limited to
±
3 mA. The addition of a 39k resistor in series with pin 5 allows
±
100V signals without damage.
Note 5:
Bar mode results when pin 9 is within 20 mV of V
+
. Dot mode results when pin 9 is pulled at least 200 mV below V
+
. LED
#
10 (pin 10 output current) is dis-
abled if pin 9 is pulled 0.9V or more below V

Note 6:
The maximum junction temperature of the LM3916 is 100C. Devices must be derated for operation at elevated temperatures. Junction to ambient thermal
resistance is 55C/W for the molded DIP (N package).
