4 / 27 page  Electrical Characteristics (Notes 2, 4) (Continued) Parameter Conditions (Note 2) Min Typ Max Units SUPPLY CURRENT Standby Supply Current (All Outputs Off) V + = + 5V, I L(REF) = 0.2 mA V + = + 20V, I L(REF) = 1.0 mA 2.4 6.1 4.2 9.2 mA mA 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 0V ≤ 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).
