Lm324 Audio Amplifier Circuit
The LM324 and LM2902 operational amplifiers are useful in a wide range of signal conditioning applications. Inputs can be powered before VCC for flexibility in multiple supply circuits. A typical application for an operational amplifier in an inverting amplifier. This amplifier takes a positive voltage on the input, and makes it a negative voltage of the same magnitude.

24/09/2016 · This is circuit schematic of audio low pass filter. By using this circuit for audio can filtering just low output frequency. Based on IC LM324 for filtering audio signal input to low frequency output. Power Supply need 9V up to 15V DC. Using DC Regulated power supply for more effieciency audio filtering and more low noise output.
The project published here is of Audio Distribution Amplifier Circuit using LM324 is shown in figure 1, which is basically a low cost, low noise amplifier designed using one of the most popular operational amplifier LM324. The circuit of audio distribution amplifier is combination of low noise input transistor amplifier and an op-amp in order ...
The tricky part to building audio amplifiers, in my opinion, is that you want only want to amplify the AC part of the signal. The picture I have attached is from H+H's Art of Electronics, 2nd Ed. The circuit I drew a red box around is just one stage, using one op-amp.
(4) For operating at high temperatures, the LM324-N/LM324A/LM2902-N must be derated based on a 125°C maximum junction temperature and a thermal resistance of 88°C/W which applies for the device soldered in a printed circuit board, operating in a still air ambient.
