1
Guaranteed by measurement of initial offset and sensitivity.
2
Sensitivity is essentially ratiometric to V
S
. For V
S
= 4.75 V to 5.25 V, sensitivity is 186 mV/V/g to 215 mV/V/g.
3
Defined as the output change from ambient-to-maximum temperature or ambient-to-minimum temperature.
4
Actual frequency response controlled by user-supplied external capacitor (C
X
, C

).
5
Bandwidth = 1/(2 × π × 32 kΩ × C). For C
X
, C
Y
= 0.002 μF, bandwidth = 2500 Hz. For C
