NOTES
1For all combinations of offset and sensitivity variation.
2Alignment error is specified as the angle between the true and indicated axis of sensitivity.
3Transverse sensitivity is the algebraic sum of the alignment and the inherent sensitivity errors.
4Specification refers to the maximum change in parameter from its initial at +25
°C to its worst case value at T
MIN to TMAX.
5Noise density (
µg/√Hz) is the average noise at any frequency in the bandwidth of the part.
6C
FILT in µF. Addition of filter capacitor will increase turn on time. Please see the Application section on power cycling.
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, VDD = +5 V,
RSET = 125 k , Acceleration = 0 g, unless otherwise noted)
