Open-drain output lets you wire-OR multiple comparator outputs on a single pull-up resistor for fault summing or window detection. ## Input offset and bias — what to expect in a production comparator Maximum input offset voltage is 7 mV at 30 V supply — typical parts are tighter, but the 7 mV ceiling is the spec you design threshold hysteresis around. Maximum input bias current is 0.25 µA at 5 V, which matters when your resistor divider string is in the megaohm range; a 10 MΩ source sees a 2.5 V error from bias alone. Quiescent current maxes at 2.5 mA per device, so two comparators in the 8-pin package draw under 5 mA total — fine for a 24 V powered module, worth watching in a battery-sensing circuit. ## Package and footprint — 8-SOIC, tape and reel No moisture sensitivity level is stated in the listing, but standard SOIC-8 typically requires baking only if the reel has been exposed to high humidity for extended periods.","metaTitle":"LM2903DRE4 Differential Comparator, -40°C to 125°C, 8-SOIC","metaDescription":"Texas Instruments LM2903DRE4 dual differential comparator.
