FXLS8471Q Anti Alias Filter design?

[robertnigbor]

For the FXLS8471Q accelerometer, what is the design of the antialias filter before the ADC?  Is the corner frequency fixed or is it adjustable?

Hi Robert,

First, sorry for the delay in answering your question.

The anti-aliasing filter is a first-order low-pass filter and its cut-off frequency depends on the ODR (dr[2:0] bits) and OSR ((s)mods[1:0] bits) settings.

Regards,

Tomas
