NTE1508 Integrated Circuit 10–Step Dot/Bar Display Driver for Linear Scale
Description: The NTE1508 is a monolithic integrated circuit in an 18–Lead DIP type package that senses analog voltage levels and drives 10 LEDs, providing a linear analog display. A single pin changes the display from a moving dot to a bar graph. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors. This feature is one that allows operation of the whole system from less than 3V. The circuit contains its own adjustable reference and accurate 10–step voltage divider. The low– bias–current input buffer accepts signals down to GND, or V–, yet needs no protection against inputs of 35V above or below GND.
