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.

Select led Colour and Mode..The user can change the LM3914 and led +Vs supply voltages.
