Dot/Bar Display Driver


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.


Features

* 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
* Inputs operate down to ground
* Output current programmable from 1 mA to 30 mA
* Input withstands +/-35V without damage or false outputs
* Outputs are current regulated, open collectors
* Directly drives TTL or CMOS
* The internal 10-step divider is floating and can be referenced to a wide range of voltages
