NU516 can sink 16 channels constant current simultaneously by the control of a single OE pin. The sink current of output channels can be set easily by an external resistor Rext. Each output channel can be connected with each other to gain higher current driving capability. With this parallel-able output capability, one NU516 can drive constant current from 3mA to 960mA being used to most types of LEDs.

More the ground area, more the heat dissipation capability that NU516 relies on. The VOUT should be as low as possible near the knee point of the output I/V curve to minimize the heat generation from NU516. An external resistors or zener diodes can be used to minimize VOUT in the output current path. The suggestion VOUT voltage is between 0.4v to 1v.
