NOTES
1Guaranteed by tests of zero g bias, sensitivity and output swing.
2Alignment of the X axis is with respect to the long edge of the bottom half of the Cerpak package.
3Cross axis sensitivity is measured with an applied acceleration in the Z axis of the device.
4This parameter is ratiometric to the supply voltage V
DD. Specification is shown with a 5.0 V VDD. To calculate approximate values at another VDD, multiply the specification by
VDD/5 V.
5Specification refers to the maximum change in parameter from its initial value at +25
°C to its worst case value at T
MIN to TMAX.
6See Figure 3.
7See Figure 2.
8CMOS and TTL Compatible.
9UCA input bias current is tested at final test.
All min and max specifications are guaranteed. Typical specifications are not tested or guaranteed.
Specifications subject to change without notice.
(TA = TMIN to TMAX, TA = +25 C for J Grade Only, VS = +5 V, @ Acceleration = 0 g,
unless otherwise noted)
