For both products, NUD4001 and NUD 4011, an external resistor allows the circuit designer to set the drive current for different LED arrays. This discrete integration technology eliminates individual components by combining them into a single package, which results in a significant reduction of both system cost and board space.
The device is available as a small surface mount package (SO–8).
