LM3914 Bar Dot LED Display Driver IC

LM3914 is a LED driver IC. It controls a BAR or DOT LED display by turning on and off depending on voltage levels and provides a linear analog display. The device does not require any programming or microcontroller and also eliminates the use of external resistors and other components. This IC features with its own reference voltage and accurate 10-step voltage divider.
