Maxim Integrated has posted details of the MAX30205 temperature sensor for thermometer applications. The sensor accurately measures temperature and provide an overtemperature alarm/interrupt/shutdown output. by Graham Prophet @ edn.com
The chip converts the temperature measurements to digital form using a high-resolution, sigma-delta, ADC. Accuracy meets clinical thermometry specification of the ASTM E1112 when soldered on the final PCB. Communication is through an I ²C-compatible 2-wire serial interface that accepts standard write byte, read byte, send byte, and receive byte commands to read the temperature data and configure the behaviour of the open-drain overtemperature shutdown output.
