Thermostat with Remote p-n Diode Sensor

It is well known that the p-n junction of a diode has a temperature coefficient of –2 mV/°C, and this fact is often used for temperature measurement. With the new MAX651x IC family from Maxim, there is now a range of integrated thermostats with external pn-junction sensors. These devices are particularly suitable for monitoring the temperature of a chip if a diode or transistor is available within the chip for use as a sensor. A two-wire connection to the remote sensor element is necessary, even if one side (DXN) lies at ground potential. Otherwise the measurement result could be corrupted by ground currents.
