CLC730131 evaluation board is configured for non-inverting gain. However, it is

possible to configure the board for inverting g

ain. 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. Cut RIN1 from input signal trace by cutting trace going from RIN1 (terminal

closest to RG1) to the input signal trace, see drawing above.

3. Add jumper wire from input signal trace to trace connecting RG1 to RT1, see

drawing above.

Changes shown for channel 1 only. Repeat these steps on the corresponding

components for the other three channels.
