Pin Compatible Upgrades for MAX924 (LTC1443)
The LTC
comparators with a built-in reference. The comparators
feature less than 8.5
μ
A supply current over temperature,
an internal reference (1.182V
±
1% for LTC1443 or 1.221V
±
1% for LTC1444/LTC1445), programmable hysteresis
(LTC1444/LTC1445) and TTL/CMOS output (LTC1443/
LTC1445) that sinks and sources current (open-drain
output for LTC1444). The reference output can drive a
bypass capacitor of up to 0.01
μ
F without oscillation.
The comparators operate from a single 2V to 11V supply
or a dual
±
1V to
±
5.5V supply (LTC1443). Comparator
hysteresis is easily programmable using two resistors and
the HYST pin (LTC1444/LTC1445). Each comparator’s
input operates from the negative supply to within 1.3V of
the positive supply. The LTC1443/LTC1445 comparator
output stage can continuously source up to 40mA. By
eliminating the cross-conducting current that normally
happens when the comparator changes logic states, power
supply glitches are eliminated.
The LTC1443/LTC1444/LTC1445 are available in the
16-pin SO and PDIP packages.
