ADT7311:  Automotive, ±0.5°C Accurate, 16-Bit Digital SPI Temperature Sensor

Product Details

Product Status:Recommended for New Designs

The ADT7311 is a high accuracy digital temperature sensor in a narrow 8-lead SOIC package. It contains a band gap temperature reference and a 16-bit ADC to monitor and digitize the temperature to a 0.0078°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). The ADC resolution is a user programmable mode that can be changed through the serial interface.
