ChemistryPrinciples of Instrumental Analysis(a) Interpretation: The amount by which v + has to exceed v − and v − has to exceed v + for the amplifier to work in limit is to be calculated. Concept introduction: Limiting condition of operational amplifier as a comparator implies that the comparator output voltage reaches the limiting value of output which is given here as +13 V on the positive side and − 14 V on the negative side. With open loop gain as A We have, v 0 + = A ( v + − v − ) = + 13 V and v 0 − = A ( v + − v − ) = − 14 V Corresponding to the positive saturation value and negative saturation value respectively. We need to find the difference in input voltage in each case.Start your trial now! First week only $4.99!*arrow_forward*
