LM64, 1C 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 diodeconnected transistor with a 16˚C offset for high temperatures.
