1 Specification
Unless otherwise stated, given minimum, typical, maximum values are corresponding values
over full performance temperature/voltage range in the normal operation mode.
In the present specification different LSB-values are mentioned; following values are valid:
- 1 LSB
ADC
≈ 0.25 mg in 2 g range; it scales with range (e. g.: 1g-range ->1 LSB
ADC
is 0.125 mg)
- 1 LSB
TEMP
= 0.5°C.
