App note: MAX31730 3-Channel remote temperature sensor

Here’s an application note from Maxim on triple remote temperature sensor: The MAX31730 temperature sensor monitors its own temperature and the temperatures of three external diode-connected transistors. The operating supply voltage is from 3.0V to 3.6V. Resistance cancellation compensates for high series resistance in circuit-board traces and the external thermal diode, while beta compensation corrects for temperature-measurement […]
