The LTC 1443/LTC1444/LTC1445 are ultralow power quad parators with a built-in reference. The parators 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. The parators operate from a single 2V to 11V supply or a dual ± 1V to ± 5.5V supply...
