TL082: question

Ivy Jin

Part Number: TL082

Hi team,

My customer would like to use TL082 in a differential proportional circuit. Is there a risk of loop instability if the amplification gain is less than 1, such as input is 10V, output is 1V?

Thanks in advance.

Regards,

Ivy

Hello Ivy,

It is not the signal gain that matters. It is the amplifier's noise gain which is the closed loop gain as viewed from the IN+ pin (when feedback is passed to IN-) .

Stability becomes a concern when extra gain or delay is added to the loop.
