I would like to know with regards to Self-Test Output Change Limits vs. Supply Voltage for ADXL345 and ADXL343 .
The measured min and max for self test values are given for Vss = 2.0 and VDD/IO =1.8V .
We are planning to use in Vss = 3.0 and Vdd/IO=3.0 .
Data sheet states For other voltages, the minimum and maximum self-test output values should be adjusted based on (multiplied by) the scale factors shown in Table 14.
I would like to know if the scale factor valid to all VDD/IO = 1.8 to Vss.
With best regards
Thanks for the question. Table 14 provides you with the valid scale factor over the Vs range, through 2.0V to 3.6V.
And it's valid for all the Vddio range.
Could you please let me know the Scale factor for Vss =3.0.
With best regards and wishes
The scale factor over Vs is only characterized at 2.5v and 3.3V in lab, but I think you can do an estimation on 3.0v based on Figure 43 and Table 14.
