DEC = decimation factor, and is determined by the selected ODR and operating mode. See Section 13.13 for more information on setting or determining

the measurement decimation factor. In LPM, the DEC factor is fixed at 1, making the time to first sample output fixed at 528.5 μs (typ), independent of the

selected ODR.

Table 8. Temperature sensor performance parameters

VDD = 1.8 V to 3.0 V, T = –40 °C to 105 °C, unless otherwise noted.

Typical values represent mean or mean ±1 σ values, depending on the specific parameter.
