Additional ACC specifications

Postby mtwardowski » Thu Mar 05, 2015 2:31 am

I am looking for additional information about the accelerometer chip. The ACC data sheet is a little sparse.

I am using the accelerometer on patient extremities and I am connecting to the MCU using a line approximately 1 meter in length. I am looking to add a low pass filter to the lines to filter out noise. The hardware manual specifies the bandwidth range of the ACC as 0-50 Hz. Could anyone give more specifics (e.g. ACC output impedance) about the chip so that I can better calculate the value of the capacitors that I require?

The accelerometer that is used in the Bitalino is the ADXL337.

You can look for further specifications in the datasheet:
