Temperature sensor operation is guaranteed in the range 2 V - 3.6 V. 2. 8-bit resolution. c. The product is factory calibrated at 2.5 V. The operational power supply range is from 1.71 V to 3.6 V. Table 5. Electrical characteristics Symbol Parameter Test conditions Min. Typ.(1) Max. Unit Vdd Supply voltage 1.71 2.5 3.6 V Vdd_IO I/O pins supply voltage(2) 1.71 Vdd+0.1 V Idd Current consumption in normal mode 50 Hz ODR 11 μA Idd Current consumption in normal mode 1 Hz ODR 2 μA IddLP Current consumption in low-power mode 50 Hz ODR 6 μA IddPdn Current consumption in power-down mode 0.5 μA VIH Digital high-level input voltage 0.8*Vdd_IO V VIL Digital low-level input voltage 0.2*Vdd_IO V VOH High-level output voltage 0.9*Vdd_IO V VOL Low-level output voltage 0.1*Vdd_IO V BW System bandwidth(3) ODR/2 Hz Top Operating temperature range -40 +85 °C 1. Typical specifications are not guaranteed. 2. It is possible to remove Vdd while maintaining Vdd_IO without blocking the communication busses. In this condition the measurement chain is powered off. 3. Refer to Table 26 for the ODR value and configuration. |
