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 and AC 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 2: Unless otherwise stated, all specifications apply with the following conditions:

Note 3: Accuracy is measured referred to +3 dB +10.000 V at pin 5, with +10.000 V at pin 6, and 0.000 V at pin 4. At lower full-scale voltages, buffer and

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 100˚C. Devices must be derated for operation at elevated temperatures. Junction to ambient thermal
resistance is 55˚C/W for the molded DIP (N package).
