ELECTRICAL CONNECTION

The part weights under 1.2 g. The size is appr. (w x h x l) 9 x 5 x 16 mm. Pin pitch is standard 100 mils.

Acceleration in the direction of the arrow will

increase the output voltage.

If the SPI interface is not used SCK (pin1), MISO (pin3), MOSI (pin4) and CSB (pin7)

must be left floating.

Self test can be activated applying logic “1” (positive supply voltage level)

to ST pin (pin 9 and 10). If ST feature is not used pins 9 and 10 must be left

floating or connected to GND.
