LTC1841/LTC1842/LTC1843
Ultralow Power Dual
Comparators with Reference
FEATURES

DESCRIPTION
The LTC
®
1841/LTC1842/LTC1843 are ultralow power dual
comparators with built-in reference (LTC1842/LTC1843).
The comparators feature less than 5.7µA supply current
over temperature, a 1.182V
±1%
reference, program-
mable hysteresis and open-drain outputs that sink cur-
rent. The reference output can drive a bypass capacitor of
up to 0.01µF without oscillation.
The LTC1841 operates from a single 2V to 11V supply or
a dual
±1V
to
±5.5V
supply. The LTC1842/LTC1843
operate from a single 2.5V to 11V supply or a dual
±1.25V
to
±5.5V
supply. The LTC1842/LTC1843 hysteresis is
easily programmed by using two resistors and the HYST
pin. The comparators’ input operates from the negative
supply to within 1.3V of the positive supply. The compara-
tors’ output stage can typically sink greater than 20mA. By
eliminating the cross-conduction current that normally
happens when the comparators change logic states, power
supply glitches are eliminated.
The LTC1841/LTC1842/LTC1843 are available in SO-8
packages.

The key to leadership is to make employees have a heart to work hard, otherwise no matter what system is in place, it will be useless.
Whether it is a work log, a weekly summary, or a monthly plan, you can write it out every day. But the key is to do it step by step. What can be done in one day takes three days. The efficiency is low...
