Typical Applications
The LED currents are approximately 10 mA, and the LM3915 outputs operate in saturation for minimum dissipation.
*
*
1/2 f/stop resolution
Ten f/stop range (1000:1)
Typical supply current is 8 mA.
This point is partially regulated and decreases in voltage with temperature. Voltage requirements of the LM3915 also decrease with temperature.
Resistor value selects exposure
Operating with a High Voltage Supply (Dot Mode Only)
