XL2901 – Voltage Comparator – Xinluda

The Xinluda XL2901 is a quad differential voltage comparator in an SOP-14 package, functionally equivalent to the industry-standard LM2901, with single-supply operation up to 36V and an open-collector output.

The Xinluda XL2901 is a quad differential voltage comparator housed in an SOP-14 surface-mount package. It integrates four independent precision comparators on a single die and is a functional equivalent of the widely deployed LM2901 family, making it a convenient drop-in option for cost-sensitive and supply-constrained designs. The XL2901 is designed to operate from a single supply across a wide voltage range and offers low input offset voltage, low input bias current, and low supply current, with an output stage compatible with TTL, MOS, and CMOS logic levels.

Key Features

• Quad (4-channel) differential voltage comparator
• Wide single-supply operation: 2V to 30V (maximum rated supply up to 36V)
• Low input offset voltage: 2mV (typ.)
• Low input bias current: 25nA (typ.)
• Low supply current: 300uA per comparator (typ.)
• Propagation delay: approximately 1.3us
• Common-mode input voltage range includes ground
• Open-collector output; compatible with TTL, MOS, and CMOS
• Operating temperature range: -40C to +125C
• SOP-14 surface-mount package
• Functional equivalent of the LM2901 quad comparator

Applications

• Limit comparators and window detectors
• Zero-crossing and level detection
• Voltage and current threshold monitoring
• Oscillators, multivibrators, and timing circuits
• Battery and power-supply supervision
• Sensor signal conditioning and interface logic

Why Source XL2901 from Pacific Component Xchange

The XL2901 is a specialty Xinluda part with limited authorized-distributor availability, which can make it difficult to procure through conventional supply channels. Pacific Component Xchange specializes in sourcing hard-to-find and obsolete power-management ICs, comparators, and optocouplers, giving your team a reliable path to parts that mainline catalogs may not stock. Every order is backed by our commitment to authenticity and quality, and we ship globally to keep your production and service operations running. If you need the XL2901 in volume, on a tight lead time, or for an end-of-life build, request a quote (RFQ) from Pacific Component Xchange and our sourcing specialists will confirm availability, pricing, and delivery for your requirement.
