... Functional Description The LM75 temperature sensor incorporates a band-gap type temperature sensor and 9-bit ADC (Sigma-Delta Analog-to- Digital Converter). The temperature data output of the LM75 is available at all times via the bus conversion is in progress, it will be stopped and restarted after the read. A ...

... The first data byte is the most significant byte with most sig- nificant bit first, permitting only as much data as necessary to be read to determine temperature condition. For instance, if the first four bits of the temperature data indicates an overtem- perature condition, the host processor could immediately take action to remedy the excessive temperatures. At the end of a ...

... D3–D4: Fault Queue: Number of faults necessary to detect before setting O.S. output to avoid false tripping due to noise. Faults are determind at the end of a conversion. See specified temperature conversion time in the electrical tables. D5–D7: These bits are used for production testing and must be kept zero for normal operation. ...
