If the gain of aninverting amplifying circuit is 13 and ±22V power supplies are used. What range of input values allows the opamp to be in linear region?(a) ±1.69(b) ±1.35V(c) ±2.28(d) ±0.5I have been asked this question during an online exam.The question is from The Inverting and Non-Inverting Amplifier Circuit in division The Operational Amplifier of Electric Circuits |

Answer» CORRECT choice is (a) ±1.69 To elaborate: 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. |
