TL494: Tl494 error amplifier

Part Number: TL494

Hı team , is the error amplifier of the tl494 linear?

Lets assume that i control the output voltage with a potentiometer , do you think that the output voltage increase linearly with the voltage on the error amplifier?

Thanks!

In my opinion, the EA have a high gain. When the error voltage increase, the output voltage will increase too. Due to this gain is very high, the error voltage varies in a very small range.
