LTC1443/LTC1444/LTC1445

Ultralow Power Quad

Comparators with Reference

FEATURES

DESCRIPTIO

■

Ultralow Quiescent Current: 8.5

µA Max

TheLTC^®1443/LTC1444/LTC1445areultralowpowerquad

comparators with a built-in reference. The comparators

feature less than 8.5µA 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 0.01µF without oscillation.

■

Wide Supply Range

Single: 2V to 11V

Dual: ±1V to ±5.5V

Input Voltage Range Includes the Negative Supply

Reference Output Drives 0.01µF Capacitor

Adjustable Hysteresis (LTC1444/LTC1445)

TTL/CMOS Compatible Outputs

Propagation Delay: 12µs (Typ) (10mV Overdrive)

No Crowbar Current

■

The comparators operate from a single 2V to 11V supply

or a dual ±1V to ±5.5V supply (LTC1443). Comparator

hysteresisiseasilyprogrammableusingtworesistorsand

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

happenswhenthecomparatorchangeslogicstates,power

supply glitches are eliminated.
