The 2V to 36V single-supply range (or ±1V to ±18V split) means this comparator can monitor a 3.3V MCU output and a 24V sensor rail on the same die. No level translator needed between the two channels. Output types include CMOS, MOS, open-drain, and TTL — the open-drain option lets multiple comparators share a common pull-up for wired-OR interrupt lines, while the CMOS rail-to-rail swing directly drives a logic input without an external resistor. The 8-SOIC (0.154-inch body width, 3.90mm) is one of the most rework-friendly packages in the catalog. The 1.27mm pitch gives plenty of room for a fine-tip iron or hot-air nozzle, and the body is small enough that the part reaches reflow temperature quickly without cooking adjacent components. Surface-mount only — no through-hole variant in this suffix.","metaTitle":"LM2903VQDRG4 Dual Differential Comparator, -40 to 125°C","metaDescription":"Texas Instruments LM2903VQDRG4 dual differential comparator.

It shares the same dual-comparator function and 8-SOIC footprint as other LM2903 variants. The LM393 is a commercial-temperature (0 to 70°C) version; the LM2903VQDRG4 extends the temperature range to -40 to 125°C and adds the wider supply range.
