Your engineering firm needs an instrumentation amplifier that provides the following input-output relationship: vO¼106vTR 3.5V. The transducer is modeled as a voltage source in series with a resistor that varies with the transducer voltage from 40 V to 750 V. Avendor is offering the amplifier shown in Figure P4–79 and the vendor agrees to make a single change to the amplifier, if needed, for no cost.

Would you recommend buying it? Explain your rationale.
