Description: Dot/Bar Display Driver

Features

* n 3 dB/step, 30 dB range n Drives LEDs, LCDs, or vacuum fluorescents n Bar or dot display mode externally selectable by user n Expandable to displays of 90 dB n Internal voltage reference from 1.2V to 12V n Operates with single supply of 3V to 25V n Inputs operate down to ground n Output current pro

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
