Industry Standard Digital Temperature Sensor in CSP Package with 2-wire Interface
The NCT475 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 temperature range.
