The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display. 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.
• Max Power Supply voltage (Vs): 25V
• Voltage on Output Drivers: 25V
• Total power dissipation (Tamb = 70°C): 1365W
• Storage and junction temperature: -55ºC to + 150ºC
