GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
The ADT7301 is a complete temperature monitoring system  
available in SOT-23 and MSOP packages. It contains a band gap  
temperature sensor and a 13-bit ADC to monitor and digitize  
the temperature reading to a resolution of 0.03125°C.  
1. The ADT7301 has an on-chip temperature sensor that  
allows an accurate measurement of the ambient tempera-  
ture. The measurable temperature range is −40°C to  
+150°C.  
2. Supply voltage of 2.7 V to 5.5 V.  
The ADT7301 has a flexible serial interface that allows easy  
interfacing to most microcontrollers. The interface is compat-  
ible with SPI®, QSPI™, and MICROWIRE™ protocols as well as  
DSPs. The part features a standby mode that is controlled via  
the serial interface.  
3. Space-saving 6-lead SOT-23 and 8-lead MSOP packages.  
4. Temperature accuracy of 0.5°C.  
5. 13-bit temperature reading to 0.03125°C resolution.  
The ADT7301s wide supply voltage range, low supply current,  
and SPI compatible interface make it ideal for a variety of  
applications, including personal computers, office equipment,  
automotive, and domestic appliances.  
6. The ADT7301 features a shutdown mode that reduces the  
power consumption to 4.88 µW with VDD = 3.3 V @ 1 SPS.
