Doubt on AD7760 INL spec

Hi,

In the datasheet, the AD7760 24 bit ADC INL spec is given as 0.00076% typ. Can you please say if this is 0.00076% of the VREF(4V) or 0.00076% of ADC FS input(3.2V)? Or is it just an absolute value = 0.0000076V (which equates to ~32LSB, LSB being 4V/2^24)? I just wanted to know the INL in terms of LSBs or absolute voltage

Thanks,

Anoop
