I WANT TO MAKE NORMAL PROJECT FOR SEE HOW TRANSISTOR WORK AS AN AMPLIFIER. I HAVE REFERED SOME REFRENCES BUT I WANT SIMPLE PRACTICALY CIRCUITWITH COMPONETS VALUES WHICH GAIN IS 10. THANKS JIGAR.

Any cons behind it... say noise etc I guess... is this a precision amplifier? Can you use this amplifier to amplify mV output span pressure sensor to V? Any cons behind it… say noise etc

I guess… is this a precision amplifier?

The TL072 is a much better choice and is even cheaper. You can see on your oscilloscope that the amplified signal has a higer rise time. Comment 24. Chuck already mentioned most arguments. mfg Esko Hello,
