关于ADC驱动器选型的问题

Other Parts Discussed in Thread: ADS1259, THS4551, THS4561

我的项目中需要为ADC选一款驱动器，目前我的ADC准备采用ADS1259，看到有一款差分放大器THS4551，其中的Applications中有24-Bit, Delta-Sigma (ΔΣ) ADC Drivers和16- to 20-Bit, Differential, High-Speed SAR Drivers，但是它的操作电压低了一点。而另外一款THS4561却只有16- to 20-Bit, Differential, High-Speed SAR Drivers，这时说THS4561就不适合做Delta-Sigma (ΔΣ) ADC Drivers吗？请问为ADC选Driver主要要看哪几项技术指标呢？
