Description
Description:-
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.
The circuit contains its own adjustable reference and accurate 10-step voltage divider.
The low-bias-current input buffer accepts signals down to ground, or V?, yet needs no protection against inputs of 35V above or below ground.
The buffer drives 10 individual comparators referenced to the precision divider. Indication non-linearity can thus be held typically to ?%, even over a wide temperature range
The following typical application illustrates adjusting of the reference to a desired value, and proper grounding for accurate operation, and avoiding oscillations.
Features:-
Drives LEDs, LCDs or Vacuum Fluorescents
Internal Voltage Reference from 1.2V to 12V
Operates with Single Supply of Less than 3V
Output Current Programmable from 2 mA to 30 mA No Multiplex Switching or Interaction between Outputs
Input Withstands ?35V 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
