EE338K HOMEWORK ASSIGNMENT #6 Op Amp Bias Parameters 1. + _ _ + R 1 =10k R 2 =90k R 3 E s E o R L =1k LM741 Use asymptotic conditions with the bias parameter values given in the Max column of the Electrical Characteristics listed (below) for the National Semiconductor LM741 Op Amp operating with T AMIN T A T AMAX and R S 10k to determine the value of the DC output voltage, E o , when E s = 0 Volts and V OS , I OS , and I B combine to produce worst case conditions for: (a) R3 = 0 Ω, (b) R3 = 9k Ω, (c) R3 = 20 k Ω. 2. + _ _ + R L =2k E o E s R 1 R 2 LM741 Using the same values for the bias parameters for the LM741 as used in problem 1, determine the largest values for R 1 and R 2 that will produce G = E o / E s = 100 and have the magnitude of the DC output voltage, E o , be no greater than 1 Volt when E s = 0 and when V OS , I OS , and I B combine to produce worst case conditions. 3.
