Dot bar led driver

Dot/Bar Display Driver Description: The NTE 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. 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. The whole display system can operate from a single supply as low as 3V or as high as 25V/5(8). The LM is a monolithic integrated circuit used as a dot/bar display driver. It specializes in sensing various levels of analog voltages to operate ten LEDs, LCDs or vacuum fluorescent displays. The current flowing through these LEDs is so programmable and regulated that it bypasses the use of current limiting resistors in series with www.doorway.ruted Reading Time: 3 mins.

• Bar or Dot Display Mode Externally Selectable logarithmic 3 dB/step analog display. One pin by User changes the display from a bar graph to a moving dot • Expandable to Displays of 90 dB display. LED current drive is regulated and programmable, eliminating the need for current • Internal Voltage Reference from V to 12V limiting resistors. The Mode pin allows you to select between "bar" mode and "dot" mode. In bar mode, all LEDs sequentially turn on. So, if the signal voltage is near max, all LEDs should be on. In "dot" mode just a single LED is on at any time. Connect mode directly to the power source for bar mode, and leave it floating for dot mode. Step Dot/Bar Display Driver for Linear Scale. Lead DIP.
