# Minimum Operating VDD

When the temperature circuit is operated in low range, the device may be operated at any operating voltage that is within the device specifications. When the temperature circuit is operated in high range, the device operating voltage, VDD, must be high enough to ensure that the temperature circuit is correctly biased.

The following table shows the recommended minimum VDD vs. Range setting.

Min. VDD, TSRNG = 1 (High Range) Min. VDD, TSRNG = 0 (Low Range)
≥ 2.5 ≥ 1.8
