* NOTICE:
Stresses above those listed under "Absolute
Maximum Ratings" may cause permanent damage to the device.
These are stress ratings only.
Functional operation of the
device at or above these conditions is not implied. Exposure to
absolute maximum rating conditions for extended periods may
affect device reliability.
ESD CONSIDERATIONS: The model 2422 accelerometer is
a CMOS device subject to damage by large electrostatic
discharges. Diode protection is provided on the outputs but care
should be exercised during handling of the cable wire ends.
Individuals and tools should be grounded before coming in
contact with the cable wire ends .

Notes:
1. Voltages AOP & AON may exceed 0.5 volt above or below the supply voltage, provided the current into or out of the wire is limited to 1mA.
2. Single ended sensitivity is half of values shown.
3. Tighter tolerances are available on special order.
4. 100g versions and above are tested from -65 to +65g.
