The supply range is 2V to 36V single or ±1V to ±18V dual. ## Output flexibility and quiescent budget The output stage supports CMOS, MOS, open-drain, and TTL logic families — you can wire the output directly to a microcontroller GPIO (open-drain with a pull-up) or drive a relay coil through a transistor. Each output sinks or sources up to 20mA typical, enough to drive a small LED or an optocoupler without a buffer. Max quiescent current is 2.5mA for both comparators combined — a modest draw that won't strain a 24V loop-powered sensor or a battery-backed monitor circuit. 8-TSSOP with 0.173-inch body width — a fine-pitch package that reflows cleanly with a standard hot-air profile. The exposed pad is absent on this one (no thermal pad to worry about), so the risk of tombstoning or solder bridging is low if the stencil aperture matches the land pattern.","metaTitle":"LM2903AVQPWRG4 Dual Differential Comparator, -40°C to 125°C","metaDescription":"Texas Instruments LM2903AVQPWRG4 dual differential comparator.
