Overview
The LM393FJ-E2 is a dual-channel analog comparator manufactured by ROHM Semiconductor, housed in an SOP-J8 surface-mount package. It operates within a supply voltage range of 3 V to 32 V and consumes approximately 600 uA of quiescent current. The device features open-collector outputs capable of sourcing up to 16 mA per channel. Key electrical specifications include a typical response time of 1 us, a maximum input offset voltage of 4.5 mV, and a typical input bias current of 250 nA. It supports ground-sensed inputs and outputs, functioning reliably across an operating temperature range from -40 C to +85 C.
Feature Summary
- Ground-sensed input and output capability allowing common mode range to ground level
- Open collector output configuration compatible with various logic families
- Low offset voltage design for precision comparison applications
Applications
- General purpose voltage monitoring circuits
- Threshold detection systems
- Over-voltage protection schemes
Procurement Notes
Verify the lifecycle status carefully before procurement, as this component is marked as Not Recommended for New Designs (NRND). Confirm that existing inventory or last-time buy options align with long-term production requirements. Ensure the SOP-J8 package dimensions match the target PCB footprint. Validate RoHS compliance documentation if required by specific regulatory standards for the end application.
Selection Notes
Select this component when a dual-channel comparator with ground-referenced input/output is required in a compact SOP-8 form factor. Consider the 1 us response time and 4.5 mV max offset voltage against system accuracy needs. Evaluate the 3 V to 32 V supply range compatibility. Note that alternative packages like TSSOP-B8 exist within the same family if space constraints differ.
Part Context
This part belongs to the LM393 series of dual independent precision voltage comparators. It shares functional similarities with other industry-standard comparators but is distinguished by its specific ROHM manufacturing parameters and SOP-J8 packaging. The series is designed for single or split supply operation, offering low current drain and high input impedance characteristics suitable for battery-powered or low-power industrial electronics.
Replacement Considerations
