If the gain of an inverting amplifying circuit is 13 and ±22V power supplies are used. What range of input values allows the opamp to be in linear region? Correct Answer ±1.69

Gain= Rf/Rs= 13 and vo= (-Rf/Rs)*vs. → vo= -13vs and given -22V≤ vo ≤ 22V. → -22= -13vs. So, vs=1.692 V → 22=-13vs. So, vs=-1.692V.
