LM64 Datasheet (Texas Instruments) - Remote Diode Temperature Sensor

LM64, Remote Diode Temperature Sensor

The LM64 is a remote diode temperature sensor with PWM fan control.

The LM64 accurately measures its own temperature and that of a remote diode.

The LM64 remote temperature accuracy is factory trimmed for a MMBT3904 diode-connected transistor with a 16°C offset for high temperatures.
