ATL432LI-Q1: Vref accuracy calculation

Hi Marc,

The reference voltage tolerance spec is listed in the datasheet as 0.5% for B grade and 1% for A grade devices at 25C.

The deviation of reference input voltage over full temperature range can also be found in the EC table as 27mV (max)

Factoring in the reference voltage accuracy, deviation across temperature, Ratio of change in reference voltage to the change in cathode voltage will provide the worst case reference voltage accuracy of the given ATL432LI-Q1 variant.

Thanks,
Joshua
