ADXL355 temperature sensor output at 25C: 1852 or 1885 LSB?

Category: Hardware
Product Number: ADXL355

ADXL355 data sheet Rev A states "TEMPERATURE SENSOR Output at 25°C 1852 LSB"

www.analog.com/.../adxl354_355.pdf

and data sheet Rev B states "TEMPERATURE SENSOR Output at 25°C 1885 LSB"

Which one is correct?

Does it depend on what revision of ADXL355 part I have?

Thanks, Ari

Hi    

The value in data sheet Rev B is correct, and it doesn't depend on the part's revision.

Hi    

After consulting with our engineering team, we determined that the standard deviation for the temperature sensor's typical output at 25°C is 27LSB. So, it seems that your temperature reading from ADXL355 is reasonable.
