NCT275 Industry Standard Digital Temperature Sensor in CSP Package with 2-wire Interface The NCT275 is a twoïwire serially programmable temperature sensor with an overïtemperature/interrupt output pin to signal out of limit conditions. This is an openïdrain pin and can operate in either comparator or interrupt mode. Temperature measurements are converted into digital form using a high resolution (12 bit), sigmaïdelta, analogïtoïdigital converter (ADC). The device operates over the –55°C to +125°C temperature range. Communication with the NCT275 is accomplished via the SMBus/I2C interface which is compatible with industry standard protocols. Through this interface the NCT275s internal registers may be accessed.
