Stand-Alone Operation
In stand-alone operation, the MAX16807 does not use

Circuits). Connecting DIN and LE to V+ provides at
least 8 external clock pulses to CLK to enable 8 out-
puts. This startup pulse sequence can be provided
either using an external clock or the PWM signal. The
external clock can also be generated using the signal
at RTCT and an external comparator.
LED Dimming
PWM Dimming
All the output channels can be dimmed simultaneously
by applying a PWM signal (50Hz to 30kHz) to OE . This
allows for a wide range of dimming up to a 5000:1 ratio.
Each channel can be independently turned on and off
using a 4-wire serial interface. The dimming is propor-
tional to the PWM duty cycle.

LED Current Amplitude Adjustment
Using an analog or digital potentiometer as R SET allows
for LED current amplitude adjustment and linear dimming.
