Features

* 1
* 2 3 dB/step, 30 dB Range
* Drives LEDs, LCDs, or Vacuum Fluorescents
* Bar or Dot Display Mode Externally Selectable by User
* Expandable to Displays of 90 dB
* Internal Voltage Reference from 1.2V to 12V
* Operates with Single Supply of 3V to 25V

Applications

* include average or peak level indicators, power meters and RF signal strength meters. Replacing conventional meters with an LED bar graph results in a faster responding, more rugged display with high visibility that retains the ease of interpretation of an analog display. The LM3915 is extremely eas
