• Manufacturer Part Number: lt1002amj
• Description: Dual, Matched Precision Operational Amplifier
• Manufacturer: Linear Technology Corporation

APPLICATIONS
The LT1002 contributes less than 5% of the total drift with
temperature, noise and long term drift of the reference.
When the upper or lower limit is exceeded the LED lights
up. Positive feedback to one of the nulling terminals
creates 5 to 20 V of hysteresis on both amplifiers. This

The accuracy of the –10V output is limited by the matching
of the two 10k resistors.
feedback changes the offset voltage of the LT1002 by less
than 5 V. Therefore, the basic accuracy of the comparator
is limited only by the low offset voltage of the LT1002.
