Rx * Ry * Vs Ry(Vo-Vs)- Rx*Vs Note 1: Output voltage deviation When the resister's stability is +/- 1% : approximately +/- 4.5% When the resister’s stability is +/- 5% : approximately +/- 8% Note 2: The temperature at surface of the case should be less than 100°C when operating. Note 3: Acertain voltage difference between input and output is required. The minimum required voltage difference can be calculated by following formula.
