LM3914 Calculator. V2 [22-Dec2013] The maximum specified LM3914 supply voltage is 25 Volts, the maximum Vrefout is 2Volts less than the LM3914 Vsupply. The maximum specified LM3914 power disappation is 1 Watt, to keep the power less than1 Watt, either reduce the led supply voltage or use a Series resistor in the led supply, the required value is displayed. In Bar mode display, led supply voltages higher than 5V will usually require a led series resistor. |
