System calibration voltage range for the AD7705

Hi All,

 

One of my customer is investigating to use AD7705 ADC.

Data sheet says, in page 6, that the “Positive Full-Scale Limit” is “1.05×VREF/GAIN”.

Does this mean that the voltage input during system calibration should be (1.05xVref)/Gain?

Or, does this mean that the voltage input during system calibration should equal Vref/Gain and maximum input voltage range during system calibration is (1.05xVref)/Gain?

 

Best Regards,

Ricky
