General
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 R11 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.
