LM3915 Calculator. V2 [22-Dec-2013]

The maximum specified LM3915 supply voltage is 25 Volts, the maximum Vrefout is 2Volts less than the LM3915 Vsupply.

The maximum specified LM3915 power disappation is 1 Watt, to keep the power less than 1 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 LM3915 and led +Vs supply voltages.
