ADI LTC1444CN#PBF

带电压基准CMOS，开路漏极，TTL12µs

Overview

The LTC1443/LTC1444/LTC1445 are ultralow power quad 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.

The LTC1443/LTC1444/LTC1445 are available in the 16-pin SO, PDIP and DFN packages.
