APPLICATION INFORMATION
By changing the time constant C1 and, the response, attack and release time, may be varied. In the above
application conditions, power dissipation may be operated at higher levels than the absolute maximum ratings.
The wattage of R is to be determined by the total LED current and R value recommended by the R table.

VCC=10~16V; R=100Ω
VCC= 8~14V; R=68Ω
VCC=6.5~12V; R=47Ω
