The typical value of DS1267's taper output resistance is 400 ohms, with a maximum value of 1000 ohms. Depending on connection method, the method's measured resistance value should be the designated value + (paralleled resistance value of the taper output resistance and remaining resistors), which accounts to up to a possible 1700 ohms.
The end-to-end resistance margin of error of a digital potentiometer is usually larger. Therefore, it is the ratio of resistance, rather than the absolute value, that is usually used in designs. When being used as a pure resistor, it is common that a digital potentiometer has a larger margin of error.
In addition, the DS1267 is no longer in production. If you plan to apply it to a new design, it is advised that you switch to other models.
