MX205Q ANALOG Data Sheet N 8/1/01
NOTES
1
Guarantee by measurements of initial offset
and sensitivity.
2
Alignment error is specified as the angle between
the true and indicated axis of sensitivity.
3
Cross-axis sensitivity is the algebraic sum of the
alignment and the inherent sensitivity errors.
4
Specification refers to the maximum change in
parameter from its initial value at 25
°
C to its
worst case value at Tmin to Tmax of the specified
temperature range.
5
Noise density (μg/
√
Hz rms) is the average noise at any
frequency in the bandwidth of the device.
6
The voltage is required to ramp full scale before
making a measurement.
7
Note: Frequency compensating circuit will achieve
160 Hz operations. See Application Note (AN-00MX-002) .
Application boards available.
8
Defined as the output change from ambient to
maximum temperature or minimum. For more
details refer to Application Note (AN-00MX-002).
9
For more details refer to Application Note
(AN-00MX-001).
10
Operating at maximum current drive capabilities,
shifting of baseline sensitivity may occur.
11
Ratiometric analog output voltage will be 44.0%
of VDD, VDA supply.
All min and max specifications are subject to change
without notification.
