adxl103 sensitivity问题

“The ADXL103/ADXL203 output is ratiometric, so the output sensitivity (or scale factor) varies proportionally to the supply voltage. At VS = 3 V, the output sensitivity is typically 560 mV/g. Sensitivity at XOUT, YOUT VS = 5 V is 1000mv ”  ,说明书上这两处,似乎有误,如果5 V Sensitivity是1000mv,3 V Sensitivity应该是600mv。

  • 按以上说法 那电压为0的时候 灵敏度为-100mv/g,明显不正确,没有电压了怎么可能有输出呢。而且说明书第三页有 “Sensitivity is essentially ratiometric to VS. For VS= 4.75 V to 5.25 V, sensitivity is 186 mV/V/gto 215 mV/V/g.”不符合3伏和5伏的线性关系
