LM324: How to Create Sine Wave Output

Click For Summary
The LM324 op-amp does not inherently produce a sine wave; it requires additional circuitry to generate such a waveform. Users often need to implement AC coupling or other configurations to achieve sine wave output. The datasheet provides guidance on designing oscillators that can produce sine waves. It is essential to understand that the op-amp functions as part of a larger circuit. Proper setup and additional components are necessary for sine wave generation.

Hello

i would like to know, how does LM324 create a sine wave after the output of the op amp??

thanks

It doesn't. What are you asking about? An opamp does nothing on its own without some other circuitry...

Are you possibly thinking of how to ac couple the op amp? This is in it's datasheet.

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
