Something more like this. This is a I could add channel mixing, so my VU meter could display both channels of audio.


Yes, but what I also wanted to prove is that you can take an IC, go to its datasheet, test around and make it work. The board is set to around mA per LED.

If you use blue LEDs 2. I'll have to learn As you can see, it uses an LM, so that's the one I bought.

The LED's just light up even with no audio source. I don't have a video on it working on microphone but there is no difference between the functionality.


I am planning to make 10 bands as this one but I want to work with smaller, smd components and then make some active filters to make a spectrum analyzer. If anyone knows a working schematic that I can modify the res and caps to change the frequencies properly I would really appreciate it. 3916 vu meter display

Ray Marston has proved, through hundreds of circuits articles and books, that he is one of the world's leading circuit designers and writers. How can YOU exercise your rights?

The schematic needs bipolar power supply to work correctly, but the negative rail can be as low as -5V or even Important- install bargraph array 3916 vu meter display U1. Do you know how to read them? May 17, 3. Chaining multiple LMs This is covered well in the data sheet, so read it for more on using two LMs.

Dot/Bar Display Driver Hookup Guide

Welcome to our site! Many of those pins can either be tied to ground, V CCor even left floating.

Other pins may require a resistor or two to set constant current or voltage values. The LED outputs are all open-collectors, so they sink current. There is no need for current limiting resistors, as the chip takes care of current regulation. Picture Information. Mouse over to Zoom - Click 3916 vu meter display enlarge. Have one to sell?

Nothing changes, always the same results. See other items More See all. Item information Condition:. See questions and answers. Share your thoughts with other customers. Here, the LEDs are all wired in series, but with each one connected to an individual output of the IC, and the IC is wired for dot-mode operation. Method of obtaining a bar display with dot-mode operation and minimal current consumption. Figure 13 shows a very useful modification which enables the above circuit to be powered from unregulated supplies within the 12 to 3916 vu meter display volt range.

Modification of the Figure 12 circuit, for operation from unregulated 12V to 18V supplies.VU METER 3916 vu meter display DRIVER DOWNLOAD - I am ready to pay cash. The power dissipation in the chip is then: The chip is essentially a constant current.


The LM is a monolithic integrated circuit that senses analog voltage levels popular VU meter One pin changes the display from a bar graph to a moving.
