Hi NXP~

I would like to ask some questions

1、In AN13761, the red place should be 1 0 0?

2. In AN12766,the red place should be 7BC0?

3. In AN12776,why is it 33℃？

4、In FXLS9XXX0_Single channel intertial sensor,data sheet

   Why exceed the maximum production range,how are their values calculated?

5、Can the range of the chip be set? How to set? Thank you very much

Hi Shawn,

please see answers to your first two questions. I will look for answers to your other three questions.

1、In AN13761, the red place should be 1 0 0?

[A] Yes, the Sensor Address in the Table 5. should be the same as the Sensor Address in the Table 4.

2. In AN12766,the red place should be 7BC0?

[A] No, The 7BFF value in the Table 12. is correct. Please refer to FXLS9xxxx and to FXLS9xxx0 datasheets. For the single axis device the Communication Error value is 7BFF. 

With Best Regards,

Jozef

Hi Shawn,

3. In AN12776,why is it 33℃？

[A] It is the TDEGG value according to the formula below the Figure 18. The values are taken from Temperature Data read (TLSB) and from the Table 25. for the 10-bit (T0LSB and Tsense).

4. In FXLS9XXX0_Single channel inertial sensor, data sheet

   Why exceed the maximum production range, how are their values calculated?

[A] Please refer to the Table 32. in the FXLS9xxx0 datasheet. The overload value can be much higher, than the maximum accelerometer value.

5. Can the range of the chip be set? How to set?

[A] The range can be set via configuration channel registers. (CFG_U3 registers). 

With Best Regards,

Jozef

Hi,Jozef

Thank you very much for your prompt reply.

for question 3.In AN12776,why is it 33℃？

TLSB = 0x06,T0LSB = -27,Tsense= 1.1,So why isn't it this value:TDEGG = (6-(-27))/1.1 = 30℃

for question 4. In FXLS9XXX0_Single channel inertial sensor, data sheet

   Why exceed the maximum production range, how are their values calculated?

I still don't know how these values are calculated,can you describe how these values are calculated? Thank you

Thanks again for your patient.

With Best Regards,

Shawn
