What are the key features of LM2901VQDRG4?
- Quad independent comparators operating from 2 V to 36 V single or ±1 V to ±18 V dual supply
- Open-collector outputs rated to 36 V allowing wired-OR configurations and flexible logic interfacing
- Input common-mode voltage range extends down to ground level enabling direct sensing of low-side signals
What is LM2901VQDRG4 used for?
LM2901VQDRG4 is commonly used in window comparator circuits, limit detection, and analog-to-digital conversion in industrial and automotive control systems. Its wide supply range and ground-referenced inputs make it ideal for battery management, power supply monitoring, and signal conditioning in environments with variable voltage rails. The quad configuration reduces BOM count in multi-channel threshold detection designs.

Frequently Asked Questions
What supply voltage range does the LM2901VQDRG4 support and how does it benefit mixed-supply designs?
The LM2901VQDRG4 operates from a single supply of 2 V to 36 V or a dual supply of ±1 V to ±18 V, giving designers flexibility to use it across 3.3 V, 5 V, 12 V, and 24 V systems without redesigning the comparator stage.
How does the open-collector output of LM2901VQDRG4 enable multi-channel fault detection?
The open-collector outputs, rated up to 36 V, allow multiple LM2901VQDRG4 outputs to be wire-OR'd together on a single fault line. This means 4 comparator channels can share one pull-up resistor, reducing component count in overcurrent or overvoltage alert circuits.
What is the maximum input offset voltage for LM2901VQDRG4 and when does it matter?
The LM2901VQDRG4 has a maximum input offset voltage of 7000 µV (7 mV). In precision threshold detection where the trigger point tolerance must be tighter than ±10 mV, this offset must be factored into the resistor divider design to avoid false triggering.
When should a designer choose LM2901VQDRG4 over a rail-to-rail comparator?
LM2901VQDRG4 is preferred when cost and wide supply range (2 V to 36 V) matter more than output swing, particularly in industrial 24 V systems or automotive 12 V rails where the ground-referenced input common-mode range and open-collector outputs suit standard relay and opto-coupler drive circuits.
