The following schematic shows how to configure the operational amplifier for non-inverting gain with split power
supply (± 2.5V). This is how the EVM is supplied from TI. This configuration is convenient for test purposes
because most signal generators and analyzer are designed to use ground-referenced signals by default. Note
the input and output provides 50-Ω termination.
