Lm324 Ic Vu Meter Circuit Diagram. The circuit was conventionally designed with eight led audio level meter made out of two low power quad op amps which utilizes lm324. At first mic picks up the sound and converts it into voltages levels linear to the intensity of sound.
Lm324 is a quad op amp ic integrated with four op amps powered by a common power supply. Vu meter circuit stereo mono 20 led with pcb. We could use an specific integrated circuit used for vu meters but we decided to use a readily available integrated circuit.
These are the maximum and the minimum common mode input signal levels that may appear across the inputs of the opamp.
Also we can easily build and cheap. It is the temperature that should not be exceeded at any cost on the ic otherwise that mat cause a permanent damage to the ic. Also we can easily build and cheap. 8 led vu meter circuit using lm324 ic.
