Temperature sensor with local and remote channels
The Maxim Integrated MAX6695YAUB+ is a digital temperature sensor that monitors both its own die temperature (local) and the temperature of an external diode-connected transistor (remote), using a 10-bit ADC for measurement resolution. Communication is over an I²C/SMBus interface, and the sensor operates from a 3V to 3.6V supply rail. It is housed in a 10-pin uMAX/uSOP surface-mount package and specified over the full -40°C to 125°C operating temperature range.
Accuracy and what it means for your thermal budget
The MAX6695YAUB+ is rated with a highest accuracy of ±3.8°C and a lowest accuracy of ±4.4°C across the full -40°C to 125°C range.
Features that matter in-system
Built-in features include a one-shot conversion mode for low-power polling, a programmable temperature limit with an output switch for overtemperature alert, and a standby mode to reduce quiescent current between measurements.
Package and handling note
The part ships in a tube. The 10-pin uMAX/uSOP footprint is shared with several other Maxim temperature sensors, so a board layout can often accommodate multiple BOM options without a respin.
