Hi Everybody
I'm experimenting with an inverting amplifier built around an LM386.
Vout should be Vin * -5. Vin is a 440 Hz Tone.
The output voltage is almost always Vin * 0.5, not Vin * 5!
If I increase input the voltage (~1.5v), the output is even less than half the input.
The circuit and the values are from my textbook. I checked multiple times that the circuit was constructed accurately. So, what would be causing this problem?
- Damaged or faulty op-amp?
- Op-amp unable to handle the 440Hz tone? (Datasheet says it's designed for audio amplification)?
Thank you very much.
