Positive feedback to one of the nulling terminals creates 5 to 20 µV of hysteresis on both amplifiers. This feedback changes the offset voltage of the LT1002 by less than 5 µV. Therefore, the basic accuracy of the comparator is limited only by the low offset voltage of the LT1002.

The accuracy of the –10V output is limited by the matching of the two 10k resistors. |
