NOTES
1Alignment error is specified as the angle between the true axis of sensitivity and the edge of the package.
2Transverse sensitivity is measured with an applied acceleration that is 90 degrees from the indicated axis of sensitivity.
3Ratiometric: V
OUT = VS/2 + (Sensitivity × VS/5 V × a) where a = applied acceleration in gs, and VS = supply voltage. See Figure 21. Output scale factor can be
doubled by connecting VOUT to the offset null pin.
4Ratiometric, proportional to V
S/2. See Figure 21.
5See Figure 11 and Device Bandwidth vs. Resolution section.
6Self-test output varies with supply voltage.
7When using ADXL250, both Pins 13 and 14 must be connected to the supply for the device to function.
Specifications subject to change without notice.
ADXL150/ADXL250–SPECIFICATIONS
(TA = +25 C for J Grade, TA = –40 C to +85 C for A Grade,
VS = +5.00 V, Acceleration = Zero g, unless otherwise noted)
