Pin Definition
VDD - This is the digital power supply input for the MX20XX. The DC voltage should be between 2.70 and
5.25 volts.
VDA - This is the analog power supply input for the MX20XX. VDA should always be connected to VDD.
GND - This is the ground pin for the MX20XX.
AOUTX - This pin is the output of the x-acceleration sensor.
AOUTY - This pin is the output of the y-acceleration sensor.
TOUT - This pin is the buffered output of the temperature sensor. The voltage at TOUT is an indication of the
die temperature. This voltage can be measured and used to compensate out the temperature dependence of
accelerometer sensitivity.
SCK - Standard product is delivered with an Internal Clock option. Ground this pin when operating with the
Internal Clock. The External Clock must be ordered special from the factory.
VREF - A reference voltage is output from this pin.
