Voltage to Bar Graph Circuit

if you want to create circuit for display 10-step voltage divider.
This device is easy way for make voltage to bar graph circuit

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. (voltage to bar graph circuit )

Features
- Drives LEDs, LCDs or vacuum fluorescents
- Bar or dot display mode externally selectable
- Expandable to displays of 100 steps
- Internal voltage reference from 1.2V to 12V
- Operates with single supply of less than
- Inputs operate down to ground
- Output current programmable from 2 mA
- No multiplex switching or interaction between
- Input withstands ±35V without damage or
- LED driver outputs are current regulated, open-collectors
- Outputs can interface with TTL or CMOS
- The internal 10-step divider is floating and referenced to a
wide range of voltages
