The typical output sink current is 20 mA, enough to drive an LED or a small relay coil through a series resistor. Input offset voltage is 2 mV maximum at 32 V supply, and input bias current is 0.25 µA maximum at 5 V. These figures define the comparator's threshold accuracy in low-side current sensing and zero-crossing detectors. Two independent comparator elements in one 8-SOIC package save board space compared to two single-channel comparators, while the open-drain outputs let multiple comparators share a common pull-up resistor for OR-ed interrupt signals. The base product number is LM2903, which covers a family of dual comparators with varying temperature grades and package options. The 'AV' suffix denotes the extended industrial temperature range; the 'Q' indicates automotive-qualified (AEC-Q100) devices in the family, though this specific variant's qualification grade should be verified against the datasheet.","metaTitle":"TI LM2903AVQDRG4 Dual Differential Comparator, 2V-36V","metaDescription":"Texas Instruments LM2903AVQDRG4 dual differential comparator.
