Dual comparator with micropower draw for always-on sense circuits
Open-drain outputs let you wire-OR multiple comparators or shift the logic level to a higher- or lower-voltage rail — useful when the comparator's supply is 5V but the downstream controller runs at 3.3V or 1.8V. Quiescent current maxes at 20µA per package, which keeps the power budget tight in battery-powered sensor nodes or always-on overvoltage/undervoltage monitors. Propagation delay is 10µs max, so this part handles slow-changing signals — thermistor thresholds, light-level detection, power-good flags — not high-speed PWM or zero-crossing at line frequency.
Industrial temp range and 8-VSSOP footprint
Input bias current is a negligible 0.04 pA at 5V, so you can use high-impedance sensor dividers without loading the source. CMRR is 75 dB typical, PSRR 80 dB — adequate for 12-bit threshold accuracy in a noisy 5V or 12V rail environment.
Output drive and open-drain wiring
Each open-drain output sinks up to 30 mA typical, enough to drive a small relay coil (with a flyback diode) or a logic input directly. Because the output is open-drain, you choose the pull-up voltage independent of the comparator supply — for example, pulling up to 1.8V for a low-voltage FPGA bank while the comparator runs from 12V. Input offset voltage is 5 mV max at 5V, which sets the practical threshold resolution floor; for precision below a few millivolts, look at a zero-drift comparator family.
Lifecycle and compliance
It is RoHS3 compliant and lead-free per the NOPB suffix.
