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°c to +80°c. The XC31B comes in a mini molded SOT-25 and USP-6B packages with a supply current of only 7µA (@VOUT=2.0V) and as such, is suitable for use with various portable devices. Output voltage is selectable in 100mV increments within a range of 2.0V to 6.0V (at 25°c).
