The ADXL375 sample rate error is not specified in the datasheet but was described in this comment as the following.
"The internal clock is factory trimmed at 25°C to be accurate within about ±2%. More than 99% of parts will be within 51Khz ±5%, which also applies to the ODR."
I have conducted a survey of 67 parts to investigate the variation in sample rate error. The sample rate was measured by configuring the ADXL375 to generate an interrupt for an ODR of 50 Hz, and measuring the interrupt signal using a Keysight 53220A frequency counter. The results are summarised in the plot below and appear in line with the comment above.
Is there an official document specifying the ADXL375 sample rate error, or must I rely on the linked comment above?
Adjust phrasing for clarity
