I want to design a voltage amplifier. I'm using the low consumption TLV2781 and a single supply op-amp desing found in page 6 ofthe following file:
I've used resistors so that the gain is around 5. The input is coming from a signal generator and the power is coming from a DC source. Now, the problem is that the signal is distorted. The distortionis not harmonic or clipping, I believe. The distortion is like linearizing the curvature of a sine signal.
Can anyone help me?! I actually used two designs and they all fail. BTW, how much distortion is allowed in an amplifier?! is it the problem with TLV2781 ?!
