The ADT7310/7320 series of 16-bit digital temperature sensors are composed of a band gap temperature reference and a 13-bit ADC that measures and converts temperature into digital format (the ADC resolution can be changed to 16-bit if required). Other features that help to monitor temperature are an open-drain output and shutdown mode that powers down the device.
Applications include medical equipment, thermal protection, environmental control, industrial process control and hand-held applications.
