Specifications subject to change without notice.
Alignment error is specified as the angle between the true axis of sensitivity and the edge of the package.
Transverse sensitivity is measured with an applied acceleration that is 90 degrees from the indicated axis of sensitivity.
Ratiometric: V
Ratiometric, proportional to V
See Figure 11 and Device Bandwidth vs. Resolution section.
Self-test output varies with supply voltage.
When using ADXL250, both Pins 13 and 14 must be connected to the supply for the device to function.
