Fig. 5: Details of Modification to Inverting Gain CLC730131 evaluation board is configured for non-inverting gain. However, it is possible to configure the board for inverting gain. To convert to inverting gain, do the following changes: How to convert the board for Inverting Gain: 1. Cut RT1 from ground plane by cutting trace going from RT1 (terminal closest to RG1) to the top ground plane. See drawing above. 2.
