If an inverting amplifying circuit has a gain of 10 and ±15V power supplies are used. The values of input for which opamp would be in the linear region?(a) ±1.25(b) ±1.5V(c) ±2.25(d) ±0.5I had been asked this question in quiz.The above asked question is from The Inverting and Non-Inverting Amplifier Circuit topic in division The Operational Amplifier of Electric Circuits |

Answer» RIGHT option is (b) ±1.5V Best EXPLANATION: Gain= Rf/Rs= 10 and vo= (-Rf/Rs)*VS. → vo= -10vs and GIVEN -12V≤ vo ≤ 12V. → -15= -10vs. So, vs= 1.5V → 15=-10vs. So, vs=-1.5V. |
