■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°C to
+80°C.The XC31B comes in a mini molded SOT-25 package with a
quiescent current of only 7µA(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°C).
