For a sensor bridge or a window comparator with 100kΩ source impedance, the 0.25µA bias adds 25mV of voltage error — that is the floor you design the hysteresis around. The 3mV offset is guaranteed across the full supply range, not just at one test point. ## Open-collector output — wired-OR and level translation Output type is CMOS, MOS, open-collector, or TTL — the open-collector stage lets multiple comparators share a pull-up resistor for a wired-OR interrupt line. Housed in a 14-SOIC (0.154\", 3.90mm width) package — the same footprint as the industry-standard LM339 in SOIC-14. Product status is Active. The base product number is LM339, a forty-year-old industry-standard quad comparator family — TI continues to manufacture the 'A' grade (lower offset) in the SOIC package.","metaTitle":"LM339ADRG4 Quad Differential Comparator, 2V–30V Supply","metaDescription":"Texas Instruments LM339ADRG4 quad differential comparator. 2V to 30V single/dual supply, 3mV max offset, 0.25µA input bias.
