**Section 5.4** 5.12 The op amp in Fig. P5.12 is ideal. a) What circuit configuration is shown in this figure? b) Find \( v_o \) if \( v_a = 1.2 \, \text{V} \), \( v_b = -1.5 \, \text{V} \), and \( v_c = 4 \, \text{V} \). c) The voltages \( v_a \) and \( v_c \) remain at 1.2 V and 4 V, respectively. What are the limits on \( v_b \) if the op amp operates within its linear region? **Figure P5.12 Explanation:** - The figure shows an operational amplifier (op amp) circuit with multiple resistors. - The resistors connected to the inverting input are 22 kΩ, 80 kΩ, and their non-inverting ends are connected to voltages \( v_a \), \( v_b \), and \( v_c \) respectively. - A 33 kΩ resistor is connected to these three along with the 22 kΩ, leading to the inverting input. - The feedback resistor is 220 kΩ between the output and the inverting input. - The output voltage \( v_o \) is taken across a 3.3 kΩ resistor connected to the output terminal. - The op amp is powered by \( \pm 6 \, \text{V} \) supplies. 5.13 a) Design an inverting-summing amplifier using a 120 kΩ resistor in the feedback path so that \[ v_o = -(8v_a + 5v_b + 12v_c). \]
