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:

3VDC ≤ V

≤ 20 VDC

−0.015V

≤ VRLO ≤ 12 VDC

TA = 25˚C, IL(REF) = 0.2 mA, pin 9 connected to pin 3 (bar mode).

3VDC ≤ VLED ≤ V

VREF,VRHI,VRLO ≤ (V

+ − 1.5V)

For higher power dissipations, pulse testing is used.

−0.015V

≤ VRHI ≤ 12 VDC

≤ VIN ≤ V+ − 1.5V

Note 3: Accuracy is measured referred to +3 dB = +10.000 VDC at pin 5, with +10.000 VDC at pin 6, and 0.000 VDC 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 VLED.

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).
