Maxim Integrated
General Description
The MAX30205 temperature sensor accurately measures temperature and provide an overtemperature alarm/ interrupt/shutdown output. This device converts the temperature measurements to digital form using a highresolution, sigma-delta, analog-to-digital converter (ADC). Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered on the final PCB. Communication is through an I2C-compatible, 2-wire serial interface.
