MSP430F6736的模拟前端

Other Parts Discussed in Thread: MSP430F6736

如附件所示：MSP430F6736说明书中有这样一段文字：

 

SD24GAINx = 1 ±910 ±920
SD24GAINx = 2 ±455 ±460
SD24GAINx = 4 ±227 ±230
SD24GAINx = 8 ±113 ±115
SD24GAINx = 32 ±28 ±29
SD24GAINx = 64 ±14 ±14.5
SD24GAINx = ±7 ±7.2

那么我在设计模拟前端电路的时候采样电压应该采多少，SD0+与SD0-的差分电压是要在920mV吗？
