Typical Applications (Continued)  
Operating with a High Voltage Supply (Dot Mode Only)  
DS005104-29  
The LED currents are approximately 10 mA, and the LM3915 outputs operate in saturation for minimum dissipation.  
*
This point is partially regulated and decreases in voltage with temperature. Voltage requirements of the LM3915 also decrease with temperature.  
Light Meter  
DS005104-30

Resistor value selects exposure  
1/2 f/stop resolution  
Ten f/stop range (1000:1)  
Typical supply current is 8 mA.
