Configuring other Components Two Channel Opamp - AD822 Positive Supply To use the same VDD as the AD5282, connect JP6. To use a separate positive supply, connect JP7 and apply positive supply(no more than +5V) to the VCC pad. Negative Supply To use GND, simply connect JP8.

2.5V Voltage Reference – ADR03 By connecting JP5, the voltage reference is connected to the A-terminal of channel-1 of the AD5282. You don’t need to worry about applying VDD because it is hardwired from the same source that is powering the AD5282.
