4–76 A requirement exists for an OP AMP circuit to deliver 12 Vto a 1-kΩload using a 4-V source as an input voltage.

Two proposed designs are shown in Figure P4–76. Some characteristics of the OPAMPthat must be used in the design are as follows:

Which of these circuits would you recommend for production and why?

(Hint: Verify that the circuits perform the required function.)
