I've spent the last few days looking into different designs of LED VU (or Peak) meters.
Most of them are based on the 3915/16 with a full-wave rectifier before them. Some just on 339s and many others on uCs.
What I can't find though is something that would fit my idea of having a meter with 4-5 LEDs. Ideally, I'm looking for:
1) 4 - 5 (or even more but not necessarily 10) LEDs that would cover a range of -20 dB to +28dB or thereabouts
2) Full wave rectified
3) Single supply voltage of around 24V
4) NO uC
There are tons of designs out there that cover one or more of the above requirements but unfortunately I can't find anything that would work in my case.
Any ideas/ suggestions are much appreciated!
