4–77 A particular application requires that an instrumentation interface delivers vO = 200vTR −5V2% to a DAC. The solution currently in use requires two OP AMPs and is constantly draining the supply batteries. A young engineer designed another tentative solution using just one OP AMP shown in Figure P4–77. As her supervisor, you must determine if her design meets the specifications
