The VOUT voltage is 10x the voltage or signal applied at VIN–, J5, but have the opposite sign. In other words, if 2 VDC is applied at VIN–, the output at VOUT is –20 VDC. For an ac input signal of 2 VPP, VOUT is 20 VPP, and phase shifted by 180°.
The general expression for the output-to-input voltage relationship for the op amp inverting-amplifier configuration is:
