General
1.5 THS4062 EVM Inverting Operation
Although the THS4062 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 on the board.
2) Move resistor R11 to the R10 location on the board.
3) Remove resistors R5 and R12.
4) Add resistors R4 and R13 with values appropriate for the input termination
required for the application.
5) Replace R1 and R9 with values appropriate for the input termination
required for the application. Typical termination value is 50 Ω.
This configuration is shown in Figure 1–3. Note that compensation capacitors
C3 and C6 are not installed.
