Page 10, table 6 of the ADXL375 spec, rate bits "1111" list an output data rate of 3200 Hz and a Bandwidth of 1600 Hz.
What is the fastest rate I can collect samples at? 1600 or 3200 Hz?
Bandwidth, in this case, is a measure of the sensor's responsiveness to dynamic conditions. The sample rate tells you how often the device produces data. If you can synchronize your reads with an interrupt service routine, you will probably want to read data at 3200 SPS. I hope that helps!
We are marking this as answered, but would encourage you to continue the conversation or start a new discussion, if you need anything else. Thanks again for posting!
