ASM121 - TEMPERATURE SENSOR ULTRA-LOW-POWER SILICON THERMISTOR

General Description

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 highaccuracy low-power temperature monitoring.

The aSM121 functions in a way that is similar to a PTC thermistor.

www.DataSheet4U.com SIMISTOR™ TEMPERATURE SENSOR ULTRA-LOW-POWER SILICON THERMISTOR aSM121 New Release Specification General Description 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 highaccuracy 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. The aSM121 output voltage ramp has a positive slope of 10mV/°C that is independent of supply voltage. The aSM121 has a guaranteed room temperature (25°C) accuracy of ±1°C.
