Q 

I would like to use a AD22037 accelerometer in a prototype, am I correct in
assuming that it's a
closed-loop pendulus accelerometer with capacitive pickoff?

A 

The ADXL203/AD22037 are dual-axis accelerometers containing a polysilicon
surface…

Q 

We would like to use your ADXL203 like a tilt sensor in safety critical
applications like platforms stability control (with humans on board). We MUST
BE SURE that your ADXL203 works well without double it.

We do not understand well the self test…

Q 

In my project i want use accelerometer ADXL203 for measurement of the corner of
the tilt. I interest what measure tilt corner each of axises to perpendicular
planes of the Earth when accelerometer is simultaneously tilt on axises X and Y
on some…

Q 

How does the ADXL203 compare to the ADXL204, when powered with 3.3V?

A 

The ADXL204 and the ADXL203 use the same silicon die.
The difference is that the ADXL204 was trimmed AND tested at 3.3V supply.
The ADXL203 was trimmed AND tested at 5V supply…

Q 

Is the ADXL103CE Rohs compliant?
 
The material declaration says 2.1milligramm PB

A 

The package is ROHS compliant until the year 2015.

It is a process related exemption. The package contains a cap.

To solder this cap at high temperatured Pb is…

Q 

Can you guarantee that sensor output sensitivity is exactly the same when using
at different frequencies?
Can you provide sensitivity vs frequency characteristics for ADXL103 or ADXL203
accelerometer sensor please?

A 

Unfortunately, I cannot confirm…

Q 

Is it allowed to operate the 2-axis sensor (+/-2g) in a x-y plain, where in
z-direction a high static
acceleration (100g) is present?

A 

No damage will be caused to the accelerometer

The datasheet (Absolute maximum ratings) says +-500g - with…
