2.1.1 Split-Supply Operation

To operate as a split supply, apply the positive supply voltage to V+, the negative supply voltage to V–, and the ground reference from supply to GND.

When operating with equal (balanced) split-supplies, the input common mode is held to GND by R12 on the bottom of the THS6232RHFEVM PCB. This configuration is default and is present upon opening the EVM for the first time.

If operating with uneven supplies, then the input common mode must be referenced to mid-supply, ((V+)+(V-))/2. For uneven supplies, this input common mode is not at GND potential. A board modification is required. Follow the steps in Section 2.1.2 for implementing uneven supplies on the THS6232RHFEVM.
