🔍 Key Concepts

• Look at which op-amp input (inverting − or non-inverting +) the Vin signal and R1 are connected to in figure A. • Recall that an inverting amplifier has the input signal going through a resistor into the inverting (−) input, with the non-inverting (+) input usually at ground, and feedback from output to the same inverting node. • A non-inverting amplifier applies Vin directly to the non-inverting (+) input, with a feedback divider from output back to the inverting (−) input. A summing amplifier has more than one input resistor feeding the same node.

💭 Think About

• Trace the path of Vin: does it go to the + input or the − input of the op-amp through R1? • Count how many separate input signals go into the amplifier in view A—does this match a summing or differential configuration? • Compare figure A’s connection of R2 (feedback) with how the feedback is arranged in a typical inverting vs non-inverting amplifier.

✅ Before You Answer

• Verify whether the non-inverting (+) input is tied to ground or to Vin. • Confirm that R2 connects from the output back to the same node that R1 and Vin connect to, forming a feedback path. • Check that there is only one input voltage source (Vin) in figure A, which rules out certain multi-input configurations.
