General Description
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 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℃).
