GENERAL DESCRIPTION  
PRODUCT HIGHLIGHTS  
The AD7314 is a complete temperature monitoring system in  
an 8-lead µSOIC package. It contains a bandgap temperature  
sensor and 10-bit ADC to monitor and digitize the temperature  
reading to a resolution of 0.25°C.  
1. The AD7314 has an on-chip temperature sensor that allows  
an accurate measurement of the ambient temperature. The  
measurable temperature range is –35°C to +85°C, with a  
2°C temperature accuracy.  
The AD7314 has a flexible serial interface that allows easy  
interfacing to most microcontrollers. The interface is compat-  
ible with SPI, QSPI and MICROWIRE™ protocol and is also  
compatible with DSPs. The part features a standby mode that  
is controlled via the serial interface.  
2. Supply voltage of 2.65 V to 2.9 V.  
3. Space-saving 8-lead µSOIC package.  
4. 10-bit temperature reading to 0.25°C resolution.  
5. The AD7314 features a standby mode that reduces the  
current consumption to 1 µA max.  
The AD7314’s low supply current and SPI-compatible interface,  
make it ideal for a variety of applications, including personal  
computers, office equipment, and domestic appliances.
