Overview
The LM2901FVJ-E2 is a ground sense comparator manufactured by ROHM Semiconductor, featuring four independent channels in an SSOP-14 package. It operates on a single power supply ranging from 3 V to 32 V with a typical operating current of 1 mA. The device provides an open collector output capable of sourcing 30 mA per channel. Key electrical specifications include a maximum input offset voltage of 1 mV, an input bias current of 20 nA, and a gain-bandwidth product of 800 kHz. It supports a slew rate of 300 mV/us and maintains operation within a temperature range of -40°C to +125°C.
Feature Summary
- Ground sense input capability allowing operation near the negative rail
- Wide single-supply voltage range for flexible power integration
- High open-collector output drive strength for direct logic interfacing
Applications
- General purpose analog signal comparison
- Voltage level detection circuits
- Threshold monitoring systems
Procurement Notes
Verify the specific suffix J against official ROHM documentation to confirm pinout compatibility and package dimensions. Confirm RoHS compliance status through the manufacturer's latest datasheet. Ensure the component meets the required thermal and electrical specifications for the target application environment before finalizing procurement.
Selection Notes
Select this component when ground-referenced input signals are required without additional level shifting. The high output current capability simplifies driving external loads directly. Consider the wide supply voltage range for applications requiring robust performance across varying power conditions.
Part Context
This part belongs to the LM2901 series of ground sense comparators. It shares functional similarities with other members like the LM2901FV but differs in package type and specific electrical tolerances. The series is designed for general-purpose comparison tasks requiring low offset voltage and high common-mode rejection.
Replacement Considerations
The LM2901FV is listed as an alias for this component family. Verify pin-to-pin compatibility and electrical parameter equivalence with any alternative parts before substitution.
