Please help me with an audio amplifier circuit using LM833N to get a gain of 10. Can you help me design procedure?

 

Hello,
for a real design please give more information about input resistance, power supply and if you need a inverting or non - inverting amplifier.

The following pictures shoes both types of amplifier with a input resistance of Ri = 10k and symmetric power supply.

R1 of the inverting circuit is equal to the input resitance of the amplifier. R3 must be equal to R1 to minimize the DC-offset of the output. The gain calculate by V = R2/R1.

R3 of the non - inverting circuit is equal to the input resitance of the amplifier. R3 must be equal to R1 to minimize the DC-offset of the output. The gain calculate by V = (R2/R1) +1.

 

Any value may be chosen for input resistance. Can you help me with the design for split supply circuit inster of dual supply +/-5V? Gain=10

 

Hello,

the following file shows jou the amplifier and the power supply.

In the drawing the German names still exist. I have copied the parts only with drop and Drag in the new drawing.

I hope it will help you. If you have more quesstions, you can ask me.

Sorry if I make mistakes in writing, because I translate the text for German to English.

Best regards

Rainer
