Comparators with Reference

DESCRIPTION
The LTC
comparators with built-in reference (LTC1842/LTC1843).
The comparators feature less than 5.7 A 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 0.01 F without oscillation.
The LTC1841 operates from a single 2V to 11V supply or
a dual
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.
