LM3914N - LED DOT/BAR Display Driver (DIP-18)
€8.50
Tax included
LM3914N LED dot/bar display driver IC (DIP-18). Converts analog signals into 10 discrete LED levels for bar or point displays.
Manufactured by Texas Instruments, it supports up to 30 mA output current and operates on 3V to 20V.
The LM3914N is a Texas Instruments integrated circuit designed to drive LED displays in dot or bar mode. It converts an analog signal into a 10-step linear visual indication, making it ideal for audio level meters, voltage indicators, or intensity gauges.
This driver integrates an operational amplifier reference and a BCD-to-decade decoder. It can drive up to 10 LEDs directly with adjustable output current, simplifying the design of analog VU meters and signal strength indicators.
