General Description

: The NTE1549 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs, or vacuum fluorescent displays, providing an electronic version of the popular VU meter.

One pin changes the display from a bar graph to a moving dot display.

LED current drive is regulated and programmable, eliminating the need for current limiting resistors.

Key Features
