NCT75 Industry Standard Digital Temperature Sensor with 2‐wire Interface The NCT75 is a two-wire serially programmable temperature sensor with an over-temperature/interrupt output pin to signal out of limit conditions.

This is an open-drain pin and can operate in either comparator or interrupt mode.

Temperature measurements are converted into digital form using a high resolution (12 bit), sigma-delta, analog-to-digital converter (ADC).

The device operates over the 55°C to +125°C tempera
