LM3914 vs LM3915 vs LM3916 - What are the differences?

[@manoharmanu1460]

Your videos are bliss for electronics hobbyist's like me . Such nice work with pcb designing and execution.

Thanks so much! I'm happy when my work is appreciated :)

Em resumo: Lm3914 e lm3916 acionam os led de forma linear, porém o 3916 é ultra rapido quando comparado ao lm3914. O lm3915 é logarítmico acionam os led de forma multiplicativa. Sendo assim os LM 3914 e 16 são mais para medidores de tensão ao passo que o lm3915 é mais voltado para sinais de áudio ou qualquer outro que seja próximo ao espectro senoidal.

[@rbaleiro]

nao, o lm3916 tbm eh escala log.

[@keithking1985]

interesting, the 3915 was more sensitive!!

[@Stefano91ste]

that's right, and it's also the IC that I use most for my Vu-Meters!

[@steinmix9448]

But slow

[@meetgaming7968]

Please sir reply ❤❤ what is the full rate of all components.example 220 micro Faraday capasitor what is voltage

[@Stefano91ste]

Hi, it is important that the voltage of the electrolytic capacitors is higher than the power supply voltage of the circuit, in this case electrolytic capacitors of 25v or above is fine.

[@meetgaming7968]

Can i don't connect dot/bar and should connect that two points with wire ? Please sir reply ❤❤

[@Stefano91ste]

Hi, sure you can. I put the pins just to give the possibility to change between DOT and BAR mode, but if you prefer to solder a wire and close the contact it doesn't change anything.

[@carriersignal]

Hi, curious to know if this chip (LM3916) offers or needs any type of calibration / adjustment, or is it already leveled and scaled correctly for reading the input of a signal properly? Thanks.

[@alaricsnellpym]

They have input pins for low and high voltage - and will measure the signal voltage's position between those two extremes. Often you tie the low voltage input to ground and the high voltage input to a suitable reference. The chip has an internal reference of something like 1.25V (I can't remember exactly) which can be used to measure a line level audio signal (should be max 1V peak to peak) so the yellow LED comes on when it hits 1V and the red ones come on if it goes over, or something like that!

[@theplaidgamer1653]

Keep up the good work!!

[@Stefano91ste]

Thank you :)

Which one works best on the signal?

[@Stefano91ste]

LM3916 for a more precise Vu-Meter

[@dyonight]

great! is it hard to implement a peak hold function as well? (when the signal hits the red leds) Thanks!

[@Enigma758]

The chip is not designed for that. It is either in "bar mode" as shown in the video, or "dot mode" which displays only one LED at any given moment to show the level. If you want peak/hold, you will probably need to use a microcontroller with a specialized program.

[@dyonight]

@@Enigma758 ok thanks!

[@bradricketts6091]

question...which IC would be better for measuring the level of the music signal on a mixer board, the preamp signal available on the output of each music channel

[@Enigma758]

Sounds like a serious application so probably the LM3916 would be best for that.

[@zeljkoadzic1692]

SIR, So who are you going to get your LM3915 from, and what are you going to do if it turns out to actually be a remarked LM3914?

[@Stefano91ste]

Hi, I generally buy LM3915s at electronics fairs.. but now thanks to the virus they are all suspended.. :( Fortunately I have always used DIP for my projects, so I have about 60 LM3915s at home that I can reuse without having to unsolder them.

[@mavic6155]

I have an Aphex 320A leveler which uses both LM3914 and LM3915. It has a problem now, which lead me to the LM3914 which is broken. The socket of this IC is melted and also the socket of the LM3915 (but this one still works... for now). Any idea what could cause these IC's to heat up so much? They might be 25 years old in the mean time, but I don't know if I should just replace them, or if I must dig a bit deeper. All IC's get 15V, according to a digital volt meter.

[@danialfikri8244]

can i use audio jack as an input

[@TheSTONEones]

Hi I'm trying to build a vu meter for a sound to light project. I've got lm3914s and 15s. 15s are better for audio vu meters. I've got all the data sheets. What I'm struggling with is what circuitry is needed to input an audio signal from a phone or as in my project a sensitive Mic amplifier some with an op amp. My hi gain op amp works ok but my LM chips are not responding. I've wired them correctly, triple checked lol. I understand the voltage divider/comparitor function. The chip will display a signal strength in the range set across pins 4 and 6. That voltage can be the internal reference voltage, manipulated if necessary or the divider can be supplied externally but not usually in most applications. How do I give the correct signal voltage/strength coming from the audio sources mentioned above is my main concern. Thank you for any advice you can give.

[@Stefano91ste]

[@itsaksharmate]

So, which ic should be best.

It depends on the use you want to make of it, for a simple Vu-Meter for example the best is LM3915

[@1954charlie]

I respect you and your work. If I praise what he does he will thank you and answer. I asked twice (for a microphone) how much the counterallas should be 2.2k (or 2.7k). I sit here looking at his pages daily. No answer, but I'm just asking for a number. You also understand what you're doing and I'm working against depression. It takes a little bit of success sometimes. My respect.

Hi Sir. This is very urgent. I was recently working on rpm meter usinf lm2917 ans 3914 from 4 months.i have cascaded 6 lm3914 .Today i completed my circuit but led arent function properly. Can you send me the circuit diagram or how to cascade them. I watched your rpm meter video but there i did not understand how you cascaded lm3914. I spent lot of efforts on it. COULD YOU PLEASE TELL ME HOW TO CASCADE 6 LM3914. PLEASE😞😞😞

Hi, in this project i cascade 5x LM3415 kzbin.info/www/bejne/hamYhXSQdtOHqLs but the diagram is the same for LM3914.. you can use this diagram for add one LM3914.. However to connect the LM391X in series it is necessary to connect pin 6 of the first with pin 4 of the second, pin 6 of the second with pin 4 of the third, pin 6 of the third with pin 4 of the fourth.. etc. PS: in my rpm meter video you can see the circuit diagram, and also in this video with the 5x LM3915 you find the diagram towards the end of the video
