Produktbeskrivning

LM3914 Dot/Bar Display Driver

The LM3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 LEDs, 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.


Features

* Drives LEDs, LCDs or vacuum fluorescents
* Bar or dot display mode externally selectable by user
* Expandable to displays of 100 steps
* Internal voltage reference from 1.2V to 12V
* Operates with single supply of less than 3V
* Inputs operate down to ground
* Output current programmable from 2 mA to 30 mA
* No multiplex switching or interaction between outputs
* Input withstands g35V without damage or false outputs
* LED driver outputs are current regulated, open-collectors
* 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
