Overview

NTE1509 Integrated Circuit 10–Step Dot/Bar Display Driver for Logarithmic Scale Description: The NTE1509 is a monolithic integrated circuit in an 18–Lead DIP type package that senses analog voltage levels and drives 10 LEDs, LCDs, or vacuum fluorescent displays, providing a logarithmic 3dB analog display.
A single pin changes the display from a bar graph to a moving dot display.
LED current is regulated and programmable, eliminating the need for current limiting resistors.
The whole display system can operate from a single supply as low as 3V or as high as 25V The circuit contains its own adjustable reference and accurate 10–step voltage divider.
The high impedance input buffer accepts signa...
