4.2 Power

This EVM features both dual- and single-supply, op-amp configurations. Power can only be applied using the header pins located at the top and bottom of the PCB. The positive supply is labeled V+, the negative supply is labeled V–, and ground is labeled GND. As an alternative, wire can be used in place of the included terminals strips to power the board directly. Figure 51 shows an all-wire assembly for a multiple feedback filter configuration.
