NTE1501

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) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 18V Circuit Voltage, VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 7.5V Input Voltage, VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16V Output Voltage, VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 16V Supply Current, ICC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 25mA Output Current, IO . . . . . . . . . . . . . . . . . . . . . . . . . . . ...
