These are stress ratings only. Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings, for extended
periods, may reduce device reliability.

Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when handling and
transporting these devices.
The human body model is a 100pF capacitor discharge through a 1.5k ? resistor pin. The machine model is a 200pF capacitor discharged directly into each pin

Notes:
1. ZXLD1360 will operate at higher frequencies but due to propagation delays accuracy will be affected.
2.100% brightness corresponds to V ADJ = V ADJ(nom) = V REF (~1.25V). Driving the ADJ pin above V REF will increase the V SENSE threshold and output
current proportionally.
