Input bias current maxes at 0.25µA at 5V, which matters when the source impedance is high (e.g., a resistive divider in a battery monitor) — that 0.25µA across a 100kΩ resistor drops 25mV, eating into the offset budget.","metaTitle":"LM2901QDRDL Quad Comparator, -40°C to 125°C, 14-SOIC","metaDescription":"Texas Instruments LM2901QDRDL quad general-purpose comparator. 2V to 30V supply, open-collector output, -40°C to 125°C range.
