Quad differential comparator with a 2 V to 32 V supply rail
It accepts a single supply from 2 V to 32 V or a dual supply from ±1 V to ±16 V, which covers most industrial and automotive rail voltages without an extra regulator.
Input offset and bias — what they mean for threshold accuracy
Maximum input offset voltage is 2 mV at 32 V supply, and maximum input bias current is 0.25 µA at 5 V. For a precision threshold (e.g., a 1% voltage monitor), the offset adds an error term you need to budget into the resistor divider. The 2.5 mA max quiescent current per package is modest — fine for a multi-channel comparator running continuously.
No last-time-buy notice, no end-of-life flag. The base product number is LM2901, a long-running TI family with broad second-source coverage across the industry.
