* 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 2012 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 on the AOP & AON signal wires may exceed 0.5 volt above or below the supply voltages provided the current is limited to 1 mA.
2. Single ended sensitivity is half of values shown.
3. Tighter tolerances available on special order.
4. 100g versions and above are tested from -65g to +65g.
