=== Thermal Diode ===
The DAC has a built in thermal diode. The diode drop from anode to cathode is typically 0.65V at 25°C. It changes at a rate of -2.20mV/°C. The anode of this diode is connected to the +5V power island, and the cathode is connected to a 270K resistor to ground. The voltage between the cathode and the resistor is connected to VIN1 (pin 15) on the ADC).
