Lm3915 Ic. 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. One pin changes the display from a bar graph to a moving dot display.
The lm3915 datasheet specifies that the ic 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. 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 ana log display. The lm3914 is a monolithic integrated circuit that senses analog voltage levels and drives 10 leds providing a linear analog display.
A single pin changes the display from a moving dot to a bar graph.
It can drive both 10 segment bar led and dot matrix led. A single pin changes the display from a moving dot to a bar graph. The lm3915 is a logarithmic display driver ic commonly used in visualizing audio signals. Dot bar display driver lm3915 datasheet lm3915 circuit lm3915 data sheet.
