The LM3914N-1 is a monolithic integrated circuit that senses analogue voltage levels and drives 10 LEDs, providing a linear analogue display. Current drive to the LEDs is regulated and programmable, eliminating the need for resistors.
- Drives LEDs, LCDs or vacuum fluorescents
- Bar or dot display mode externally selectable by user
- Expandable to displays of 100 steps
- Inputs operate down to ground
- No multiplexing switching or interaction between outputs
- LED driver outputs are current regulated, open-collectors
- Outputs can interface with TTL or CMOS logic
