The LTC
1540 is an ultralow power, single comparator
with built-in reference. The comparator’s features
include less than 0.6
μ
A supply current over the commer-
cial temperature range, a 1.182V
±
2% reference, pro-
grammable hysteresis and TTL/CMOS outputs that sink
and source current. The reference output can drive a
bypass capacitor of up to 0.01
μ
F without oscillation.
The comparator operates from a single 2V to 11V supply
or a dual
±
1V to
±
5.5V supply. Comparator hysteresis is
easily programmed by using two resistors and the HYST
pin. Each comparator’s input operates from the negative
supply to within 1.3V of the positive supply. The compara-
tor output stage can continuously source up to 40mA. By
eliminating the cross-conducting current that normally
occur when the comparator changes logic states, power
supply glitches are eliminated.
The LTC1540 is available in the 8-pin MSOP and SO
packages.
