AD7799
Table 7 shows the AD7799 output rms noise for some update rates and gain settings. The numbers given are for the bipolar input range with a 2.5 V reference. These numbers are typical and are generated with a differential input voltage of 0 V.
Table 8 shows the effective resolution, and the output peak-to-peak resolution is given in parentheses. Note that the effective resolution is calculated using the rms noise, whereas the peak-to-peak resolution is based on peak-to-peak noise. The peak-to-peak resolution represents the resolution for which there is no code flicker. These numbers are typical and are rounded to the nearest LSB.
参考电用电阻分电源的压就行,实际效果看你整个系统的设计了,不光是电路的可能还有机械部分的影响 |
