2024年1月3日 · Here, I will elucidate the datasheet of the IC LM3915, its pinout functions, its main electrical specifications, and also a few useful application circuits. The LM3915 is a monolytthic IC designed to sense analogue voltage signals, and produce an incremental or sequential logic switching across its 10 output.

The LM3915 is a monolithic integrated circuit that senses analog voltage levels and drives ten LEDs, LCDs or vacuum fluorescent displays, providing a logarithmic 3 dB/step analog display. One pin changes the display from a bar graph to a moving dot display.

Description: Dot/Bar Display Driver. Manufacturer: National Semiconductor (TI).

LM3915 is a single-chip integrated circuit that can drive ten LED, LCD or vacuum fluorescent displays by sensing an analog voltage volume into a digital amount. It provides an analog display of order 3dB/, which can be set to a dot or bar display through the MODE foot.

The LM3915 is a monolithic integrated circuit (IC) designed to function as a linear analog display driver. It's commonly used in various applications where analog voltage levels need to be visually represented, such as audio level meters, VU meters, battery charge indicators, and more.

The LM3915 offers a simple way to display a logarithmic voltage level using one or more groups of ten LEDs with a minimum of fuss. If you’re wanting to make a VU meter, you should use the LM3916 which we will cover in the final instalment of this trilogy.
