Power Connections

The EVM features banana jack connections for VCC, VEE, and GND. Connect the positive supply to VCC, the negative supply to VEE, and the ground reference to GND to use the board in split supply configurations. The VEE and GND inputs should be connected to ground for single supply operation. It is important to note that the input and output resistors will be refererenced to the lowest supply voltage instead of a mid-supply voltage as in the split-supply configuration when using the board in a single supply configuration.

It is very important to include the reccomended power supply decoupling capacitors in order to reduce the risk of device oscillations. The smallest valued capacitors should be placed in the footprints closest to the OPA3S2859-EP footprint to provide good high frequency decoupling.
