IIM-42352 strange output when submitted to amplitude greater than the full-scale

By jbianchettitra… , 11 April 2025

Hi. We have a IIM-42352 sensor configured for 16KHz of ODR, ±16g of Full-Scale range, FIFO mode and INTF_CONFIG0.FIFO_HOLD_LAST_DATA_EN register bit set to 1.

We are observing that when the sensor is submitted to an amplitude greater than 16g, sometimes the output goes down to -32768 (as shown in the attachments). We couldn't find any information in the datasheet about the behavior on these conditions, if it's normal or the value should be clipped at the positive value.
