LM3915 - DOT Bar Display Driver

R45.00Price

Internal reference Voltage: 1.2V - 12V

Drives: LEDs, LCDs or Vacuum Fluorescents

The LM3915 is a monolithic IC that senses analog voltage levels and drives 10 LED's providing a logarithmic 3dB/step with a range of 30dB. A single pin changes the display from a moving dot to a bar graph. Current dives to the LED's is regulated to programmable, eliminating the need for resistors. This feature is one that allows operation of the whole system from less than 3V.

 

Power Dissipatio: 1365mW 

MAX Supply Voltage: 25V 

MAX Output Voltage: 25V

Load: 10mA
