Lm3914. It can drive up to 10 leds lcds or vacuum fluorescent displays on its outputs. It eliminates the need for programming a microcontroller and also reduces the hardware required to drive the 10 leds.
Lm3914 is an analog controlled led driver ic. A high input impedance buffer operates with signals from ground to 12v and is protected against reverse and overvoltage signals. It eliminates the need for programming a microcontroller and also reduces the hardware required to drive the 10 leds.
Lm3914 is a chip which drives 10 led based on linear input voltage value.
Lm3914 is an analog controlled led driver ic. The lm3914 is an 18 pin chip. A single pin changes the display from a moving dot to a bar graph. The pinout of the lm3914 is shown below.
