When the upper or lower limit is exceeded the LED lights
up. 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 LT1002 contributes less than 5% of the total drift with
temperature, noise and long term drift of the reference.
The accuracy of the –10V output is limited by the matching
of the two 10k resistors.
