description
LTC®1443 / LTC1444 / LTC1445is an ultra-low power quad comparator with a built-in voltage reference. These comparators haveof supply current(Over the entire temperature range), an internal benchmark(LTC1443for1.182V±1%whereasLTC1444 / LTC1445is1.221V±1%), programmable hysteresis(LTC1444 / LTC1445)and those that can absorb and supply currentTTL / CMOSoutput(LTC1443 / LTC1445aboutLTC1444is an open-drain output)。 The reference output can drive a UP GUUM0.01μFof bypass capacitors without oscillation.
Comparator adoption2Vreach11VSingle operating power supply or±1Vreach±5.5VDual operating power supplies(LTC1443)。 Comparator hysteresis can easily be used with two resistors and HYSTPins(LTC1444 / LTC1445)to set it up. The input of each comparator operates from the negative supply to the positive supply1.3VWithin.LTC1443 / LTC1445The comparator output stage can supply up to continuously40mAof current. Power supply interference is eliminated by eliminating cross-conduction currents that are common when comparators change logic states.
