The differential instrumentation amplifier shown in Fig. 6.56 must have a voltage gain of 10³with an accuracy of 0.1 percent. What is the minimum required open-loop gain of the op amp? Assume the op amp open-loop gain has a tolerance of +100 percent, 50 percent. Neglect the effects of R_inand R_outin the op amp.
