Overview
The ADT7310TRZ-REEL, produced by Analog Devices Inc., is a high-accuracy digital temperature sensor packaged in an 8-lead narrow SOIC. This device incorporates a band gap temperature reference and a 13-bit analog-to-digital converter (ADC) to monitor and digitize temperature with a resolution of 0.0625°C. The ADC resolution can be enhanced to 16 bits (0.0078°C) by configuring the device. The ADT7310 is designed for applications requiring precise temperature measurement over a wide temperature range of −55°C to +150°C and operates with a supply voltage of 2.7 V to 5.5 V.
