NTE1500 & NTE1501  
Integrated Circuit  
7–Step LED Driver Circuit  
Description:  
The NTE1500 and NTE1501 are integrated circuits designed for driving 7–dot LED displays. The  
NTE1500 responds logarithmically to the input signal while the NTE1501 responds linearly. Because  
an adjustment pin for output current is provided, the brightness of the LED can be controlled.  
Features:  
D Linear (NTE1501) and Logarithmic (NTE1500) Response  
D 7–LED Bar Graph Display Driver  
D Brightness is Externally Adjustable  
D High Output Current: 25mA Max  
D Series Connection Capable for Driving more than 7–Dot Displays  
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
