The ASM121 is a high-precision, 3-lead CMOS silicon thermistor in an ultra-small leadless package that provides a cost-effective solution for applications requiring high-accuracy low-power temperature monitoring. The aSM121 functions in a way that is similar to a PTC thermistor.

However, it is linear-calibrated, enabling application developers to directly interpret output voltage as
temperature without complex compensation for nonlinearity.
