1.5 THS4012 EVM Inverting Operation

Although the THS4012 EVM is shipped preconfigured for dual-channel

noninverting operation, it can be reconfigured for inverting operation by

making the following component changes:

1) Move resistor R3 to the R2 location and R5 to the R4 location on the board.

2) Move resistor R1 1 to the R10 location and R13 to the R12 location on the

board.

This configuration is shown in Figure 1–3. Note that compensation capacitors

C3 and C6 are not installed.
