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:
Linear (NTE1501) and Logarithmic (NTE1500) Response
7–LED Bar Graph Display Driver
Brightness is Externally Adjustable
High Output Current: 25mA Max
Series Connection Capable for Driving more than 7–Dot Displays
