LM3914 Dot or Bar Display Driver IC
₹85.00 inc. GST
The LM3914 is a linear LED driver IC that converts analog voltage into a 10-LED dot or bar display. Ideal for battery indicators, VU meters, and measurement projects.
The LM3914 Dot or Bar Display Driver IC is a versatile analog level display driver designed to drive up to 10 LEDs, LCDs, or vacuum fluorescent displays. This IC converts analog voltage signals into a proportional LED display, making it ideal for battery level indicators, audio level meters, temperature displays, and various measurement applications.
The LM3914 features both dot mode and bar mode operation, allowing users to select between displaying a single LED at a time (dot mode) or a continuous LED bar graph (bar mode). It requires minimal external components, supports wide voltage ranges, and provides accurate linear output.
With its internal voltage reference and adjustable LED current, the LM3914 simplifies circuit design while ensuring reliable performance. It is widely used in electronics projects, educational kits, DIY robotics, and embedded system applications.
