MAX31732 Multi-Channel Temperature Sensor

Analog Devices MAX31732 Multi-Channel Temperature Sensor monitors up to four external diode-connected transistors and its own temperature. A resistance cancellation feature compensates for up to 300Ω of series resistance between the external thermal diode and the MAX31732. At the same time, beta compensation corrects for temperature measurement errors due to low-beta sensing transistors. The sensor also allows ideality factors between 0.9844 and 1.311.
