Digital Temperature Sensor ICs

I2CBUS compatible digital temperature sensor ICs that incorporate a temperature sensor and a sigma-delta AD converter

Temperature Switch ICs

Temperature switch ICs sense the ambient temperature of the IC and switch the IC output at the detected temperature

Analog Temperature Sensor ICs

High-accuracy temperature sensor IC that can linearly output the voltage in response to changes in temperature
