LM3914 DOT / BAR DISPLAY DRIVER
The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10LEDs, providing a linear analog display. A single pin changes the display from a moving
dot to a bar graph. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors. This feature is one that allows operation of the whole system from less than 3V.
* Drives LEDs, LCDs or vacuum fluorescents.
* Bar or dot display mode externally selectable by user.
* Expandable to displays of100steps.
* Internal voltage reference from 1.2V to 12V.
* Operates with single supply of less than 3V.
* Inputs operate down to ground.
* Outputcurrentprogrammablefrom2mAto30mA.
* No multiplex switching or interaction between outputs.
* Input with stands 35V without damage or false outputs
* .LED driver outpu sare current regulated,
* Outputs can interface with TTL or CMOS logic.
* The internal 10-step divider is floating and can be
referenced to a wide range of voltages.
