Dual-limit-microvolt-comparator


Posted on Mar 15, 2013

When the upper or lower limit is exceeded, the LED lights up. Positive feedback to one of the nulling terminals creates 5 to 20 p,V of hysteresis on both amplifiers. This feedback changes to offset voltage of the LT1002 by less than 5 p,V.

Therefore, the basic accuracy of the comparator is limited only by the low offset voltage of the LT1002.
