■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 7

μA

Output voltage is selectable in 100mV

increments within a range of 2.0V to 6.0V (at 25

℃).

■APPLICATIONS

●Mobile phones

●Portable AV equipment

●Palm top computers, PDAS

●Battery powered equipment
