The CMOS push-pull rail-to-rail output drives logic inputs directly — no external pull-up resistor, which saves board space and one BOM line. ## Hysteresis and propagation delay — what they mean for the threshold decision Built-in 4 mV hysteresis prevents output chatter when the input signal crosses the threshold slowly — a thermistor voltage or a ramp from a current-sense amplifier will not trigger multiple edges. Maximum propagation delay is 940 µs — the comparator takes under a millisecond to change state. For a battery-protection circuit or a slow over-temperature latch this is ample; for a high-speed PWM or zero-crossing detector it is the ceiling that limits the switching frequency. ## Active lifecycle and compliance posture ROHS3 compliant, with a CMRR of 66.02 dB typical and PSRR of 80 dB typical — the supply-rejection figure means the threshold stays stable even when the battery voltage droops under load.","metaTitle":"MAX919ESA+ Comparator, 1.2µA, 8-SOIC, Active","metaDescription":"Analog Devices MAX919ESA+ general-purpose comparator, 1.2 µA quiescent, rail-to-rail CMOS output, 8-SOIC.
