Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which
guarantee 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
comparator offset voltage may add significant error. See table for threshold voltages.
Note 4: Pin 5 input current must be limited to
Note 5: Bar mode results when pin 9 is within 20 mV of V
disabled 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).
