Working Principle of LM95231BIMM-1

The LM95231BIMM-1 is a digital temperature sensor that utilizes an analog-to-digital converter to convert analog temperature values into digital output. It uses an integrated thermal diode to sense temperature, which is then converted into a voltage signal. This voltage signal is then input through an on-chip voltage reference and comparator to an ADC, which converts it into a digital value. The digital value is then transferred to the two-wire interface, which is used to communicate with the host processor.[3]

The LM95231BIMM-1 also has temperature protection features such as automatic shutdown of the thermal diode if the temperature exceeds the programmed temperature limit. This prevents damage to the sensor and also keeps the system functioning properly. The sensor features low power consumption and can operate in temperatures from -55°C to +125°C with linearity and accuracy of ±0.5°C. It also features an on-chip voltage buffer, which enables the user to accurately determine the temperature and write data to the sensor. [4]
