- 5.26The op amp in the circuit of Fig. P5.26 is ideal. - a. What op amp circuit configuration is this? - b. Find an expression for \( v_{o} \) the output voltage in terms of the input voltage \( v_{a} \). - c. Suppose \( v_{a}=162 \mathrm{mV} \). What value of \( R_{f} \) will cause the op amp to saturate? (b) \( v_{o}=15-2 v_{a} \) (c) \( R_{f}=11,852 \Omega \), the other value is not possible since \( R_{f} \) is negative
