LM3915 LED Dot/Bar Display Driver IC DIP 18 Package

LM3915 LED Dot/Bar Display Driver IC DIP 18 Package The LM3915 is a LED dot/bar display driver IC designed to display analog signal levels in a visually intuitive form. It drives 10 LEDs in either dot mode or bar mode, making it ideal for applications such as audio level meters and signal strength indicators.Unlike linear display drivers, the LM3915 features a logarithmic (3 dB per step) response, which closely matches the human perception of sound intensity. The IC integrates a precision voltage reference, comparator ladder, and LED drivers, allowing operation with a minimal number of external components. Packaged in a DIP-18 through-hole package, the LM3915 is ideal for prototyping, educational, and industrial display applications.Click here to view related productsFeaturesDrives 10 LEDs in dot or bar display modeLogarithmic scale (3 dB per step) suitable for audio signalsBuilt-in precision voltage referenceOn-chip LED current regulationAdjustable display sensitivityWide supply voltage rangeLow power consumptionCascadable for extended displaysSimple external component requirementDIP-18 package for easy PCB mounting and prototypingApplicationsAudio level (VU) metersSound and music visualizersSignal strength indicatorsBattery and power level indicatorsTest and measurement equipmentIndustrial monitoring panelsConsumer audio equipmentlm3915-ic-datasheet*Product image for illustration purposes only, actual product may vary.
