I'm using ADXL372 for evaluating purpose.
Using SPI i'm able to read/write internal registers. ( Register Read only value are ok)
Meanwhile, when i'im setting ODR to 6400/3200/1600 or so, and checking INT on ADXL pin, i see Data rate @7022 / 3250 / 1625 Hz
(no reading value, only configuring register, no fifo, etc)
Is it normal?
Thanks for the question. Yes, the ODR is based on the system clock which has up to 15% variation. You can find this information on Figure 23 of the datasheet.
