1
Alignment error is specified as the angle between the true and indicated axis of sensitivity, (see Figure 2).
2
T ransverse sensitivity is measured with an applied acceleration that is 90
°
from the indicated axis of sensitivity. T ransverse sensitivity is specified as the percent of
transverse acceleration that appears at the V
output. T his is the algebraic sum of the alignment and the inherent sensor sensitivity errors, (see Figure 2).
3
Specification refers to the maximum change in parameter from its initial at +25
°
C to its worst case value at T
MIN
to T
MAX
.
4
Frequency at which response is 3 dB down from dc response assuming an exact C1 value is used. Maximum recommended BW is 10 kHz using a 0.007
μ
F capacitor, refer to
Figure 22.
5
Applying
logic high to the self-test input has the effect of applying an acceleration of –52.6
g
to the ADX L50.
6
Input offset voltage is defined as the output voltage differential from 1.800 V when the amplifier is connected as a follower (i.e., Pins 9 and 10 tied together). T he voltage at
Pin 9 has a temperature drift proportional to that of the 3.4 V reference.
