5.3The op amp in the circuit in Fig. P5.3 is ideal.
Ans vo = -12V
• a. Calculate vo if va = 1.5V and vp = 0V.
• b. Calculate voif va = 3V and vp = OV .
• c. Calculate v, if va = 1V and vp = 2V.
Ans vo= -24V saturated at - 18V
Ans vo= 10V
. d. Calculate vo if va = 4V and vp = 6V.
Ans vo = 22V saturated at vo = 18V
• e. If v = 4.5V, specify the range of va such that the amplifier does not saturate.
