is not being able to find it's datasheet anywhere on the net.
It's dimensions & pin positions are same as of AD22282/83/86. whether it is
1/2/3 axis accelerometer or it's pinouts & whether they are different from
The AD22290 is an obsolete special based on the ADXL311 (pretty old). It is
specified as a 2 axis analog output accelerometer with 3V supply voltage. You
can look at the ADXL311 data sheet for pin out, etc.
