How to express BGR accuracy in ppm?

[cheenu2002]

Hi,
I would like to know how to get the BGR output accuracy interms of ppm/degreee Celcius. I think for a 1.2 V BGR, 1 ppm = 1.2 uV. If my total BGR output variation is 12 mV across the temperature range -40 to 125, then what will be my accuracy?

hi..

hope this formula helps finding out the PPM..

Thanks
