LM95231 Datasheet (National Semiconductor) - TruTherm Precision Dual Remote Diode Temperature Sensor

LM95231, TruTherm Precision Dual Remote Diode Temperature Sensor

The LM95231 is a precision dual remote diode temperature sensor (RDTS) that uses National’s TruTherm technology.

The 2-wire serial interface of the LM95231 is compatible with SMBus 2.0.

The LM95231 can sense three temperature zones, it can measure the temperature of its own die as well as two diode
