Overview
The LM2901FJ-E2 is a quad ground-sense comparator manufactured by Rohm Semiconductor, housed in a 14-SOPJ surface-mount package. It operates on a single supply voltage ranging from 3V to 32V or dual supplies of ±1.5V to ±16V. The device features an open-collector output capable of sourcing up to 16mA. Key electrical specifications include a maximum input offset voltage of 4.5mV at 5V and a typical input bias current of 50nA. It supports a wide operating temperature range from -40°C to +125°C.
Feature Summary
- Ground-sense input and output capability allowing operation near the ground potential.
- Wide operating supply voltage range compatible with various power systems.
- Open-collector output structure for flexible interfacing.
- Integrated electrostatic protection circuit.
Applications
- General-purpose analog signal comparison
- Voltage level detection circuits
- Threshold sensing applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific tape-and-reel packaging requirements. Ensure the supplier provides valid traceability documentation. Review the latest datasheet for any design-in restrictions or lifecycle notices before finalizing procurement plans.
Selection Notes
Select this component when ground-referenced input signals are required within a wide voltage window. The low offset voltage ensures accurate threshold detection. Verify that the 14-SOPJ package dimensions fit the target PCB layout. Consider the open-collector output requirement for external pull-up resistor implementation in the circuit design.
Part Context
This part belongs to the LM2901 series of quad comparators. It shares functional similarities with other members like the LM2901FV but differs in package type. The SOPJ package offers a compact footprint suitable for space-constrained designs. It serves as a general-purpose solution for basic comparison tasks without requiring complex external components.
Replacement Considerations
The LM2901FV-E2 is listed as a manufacturer-recommended substitute. Verify pin compatibility and package differences between the SOPJ and alternative packages before substitution.
