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 (% Duty Cycle
√
/Hz) 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.
8
Defined as the output change from ambient to
maximum temperature or minimum. Output change
expressed in % change of duty cycle.
