LM3915N Led Dot/Bar Display Driver HLF DIP-18 LM3915N

Product Overview: LM3915N (HLF / Honglifa)

The LM3915N, manufactured by HLF (Shenzhen Honglifa), is a monolithic 10-step logarithmic display driver integrated circuit. It is specifically designed to sense analog voltage levels and drive ten LEDs, LCDs, or vacuum fluorescent displays. Due to its logarithmic internal scaling, it is the industry-standard choice for audio applications, such as creating VU (Volume Unit) meters, as it accurately mimics the human ear's perception of sound intensity by providing 3 dB per step resolution.
