• Manufacturer Part Number: AD7314_03
• Description: Low Voltage, 10-Bit Digital Temperature Sensor in 8-Lead MSOP
• Manufacturer: AD [Analog Devices]

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD7314 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
