Question:

Your engineering firm needs an instrumentation amplifier that provides the following input-output relationship: \(v_{\mathrm{O}}=10^{6} v_{\mathrm{TR}}-3.5 \mathrm{~V}\). The transducer is modeled as a voltage source in series with a resistor that varies with the transducer voltage from \(50 \Omega\) to \(500 \Omega\). A vendor is offering the amplifier shown in Figure P4-67 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.
