adxl202 + 18f452

hi

what is the circuit conditionning needed to use the analog output from the adxl202 instead of the pulse output

thanks for help
 

Just an OP-AMP (and a low pass...) as it says in the datasheet:

"XFILT, YFILT Output
The second method is to use the analog output present at the
XFILT and YFILT pin. Unfortunately, these pins have a 32 kΩ
output impedance and are not designed to drive a load directly.
An op amp follower may be required to buffer this pin. The
advantage of this method is that the full 5 kHz bandwidth of the
accelerometer is available to the user. A capacitor still must be
added at this point for filtering."
