LTC1440/LTC1441/LTC1442
Ultralow Power Single/Dual
Comparator with Reference
FEATURES

DESCRIPTION
The LTC
廬
1440/LTC1441/LTC1442 are ultralow power
single and dual comparators with built-in references. The
comparators feature less than 3.7碌A supply current over
temperature (LTC1440), a 1.182V
鹵1%
reference, pro-
grammable hysteresis (LTC1440/LTC1442) and TTL/CMOS
outputs that sink and source current. The reference output
can drive a bypass capacitor of up to 0.01碌F without
oscillation.
The comparators operate from a single 2V to 11V supply
or a dual
鹵1V
to
鹵5.5V
supply (LTC1440). Comparator
hysteresis is easily programmed by using two resistors
and the HYST pin (LTC1440/LTC1442). Each comparator鈥檚
input operates from the negative supply to within 1.3V of
the positive supply. The comparator output stage can
continuously source up to 40mA. By eliminating the
cross-conducting current that normally happens when the
comparator changes logic states, the power supply glitches
are eliminated.
The LTC1440 is available in 8-pin PDIP, SO and MSOP
packages. The LTC1441/LTC1442 are available in 8-pin
PDIP and SO packages.
