About the ADS1271EVM-PDK power supply with buffer amplifiers

Other Parts Discussed in Thread: OPA1632

In the "ADS1271EVM & ADS1271EVM-PDK User's Guide", it is said that "J3 provides connection to the common power bus for the ADS1271EVM."(Pg 4) For J3.1 and J3.2,they stand for "+AVDD: +15V to power buffer amplifier"and"–AVDD: –15V to power buffer amplifier section".(Pg 4) If I use these two "OPA1632" buffer amplifiers, should I connect +/- 15V reference supply with these two pins respectively, shouldn't I? If so, I can supply these two reference voltages by on "+/- VA "pins on MMB0 board or "J4.3/J4.4","J5.3/J5.4" on EVM(Pg 3),right?

Thanks a lot!
