2.1 Power Supplies

The JFE150EVM is configured by default to operate from a single supply voltage of VDD = 12 V and VSS = GND. VSS can be tied to GND by using a short BNC cable from the VSS banana jack to any GND banana jack shown in Figure 4-2. If dual-supply operation is required, VSS can be powered separately; adjust components R25 and R12 to bias the JFE150 to the desired bias point. Set Vbias to midsupply, as discussed in section Section 2.3.
