關於AD7380 的 typical circuit application 是否可用 Single-Ended to differential Conversion with a Fully Differential Amplifier模式設計?

Hi 
Q1.假設 dual-channel 只用到1個其中ch-A ,則 Pin14 SDOB/ALERT 是否需要預留GPIO控制或是可floating?
Q2.先前用AD4001替換為AD7380,而 AD7380應用上否可以參考AD4001 Single-Ended to differential Conversion with a Fully Differential Amplifier方式設計?
AD7380 typical reference circuit 看起來為Multiple Supplies.
感謝.
