20-Pin SOIC Package

N/C pins are recommended to be left FLOATING

−Y

Acceleration of the package

in the +X and +Y direction

(center plates move in the −X

and −Y direction) will result in

an increase in the X and Y

outputs.

Activation of Self test moves the

center plates in the −X and −Y

direction, resulting in an increase

in the X and Y outputs.
