Note 2:
Enough current should be supplied into the VCC lead to keep the internal 15.6V zener clamp diode on this lead
regulating its voltage, VCLAMP.
Note 3:
The MAX lead is a voltage-controlled current source. For optimum dim interface current mirror performance,
this current should be kept between 0 and 750
µA.
Recommended Operating Conditions
For proper operation the device should be used within the recommended conditions.
