As part of the 16-WFQFN Exposed Pad package.Devices with SPI interfaces provide better data acquisition performance.Surface Mount-axis mounts the part.If your meter doesn't read 2.7V~3.6V for the supply voltage as this unit is designed you better redo the circuit.I would expect the average operating temperature for this chip to be -40°C~85°C TA degrees Celsius.As well as providing voltage reference for External Internal, it also provides current reference for External Internal.As long as a current of 500μA is applied to this device, it will work in compliance with its designed specifications.16-QFN (3x3) supplier provides device package.
