The XC31B Series are ultra small CMOS temperature sensor ICs. As a bandgap type temperature sensor is built-into the XC31B, linearity, in comparison to thermistor type temperature sensors, is much better. The operating temperature range of the Series is from -30℃ to +80℃. The XC31B comes in a mini molded SOT-25,USP-6B package with a quiescent current of only 10mA (2.0V) and as such, is suitable for use with various portable devices. Output voltage is selectable in 0.1V steps within a range of 2.0V to 6.0V (at 25℃).
