Overview
The BA2903SFV-E2 is a dual-channel analog comparator manufactured by ROHM Semiconductor, designed for general-purpose applications. It operates within a supply voltage range of 2 V to 36 V and features an open collector output type with a differential input configuration. Key electrical parameters include a typical response time of 1.3 µs, a maximum input offset voltage of 2 mV, and a working supply current of 600 µA. The device supports a channel output current of 16 mA and functions reliably across an operating temperature range from -40°C to +105°C. It is housed in an MSOP-8 surface-mount package.
Feature Summary
- Dual-channel architecture providing two independent comparison circuits within a single compact package.
- Open collector output structure allowing flexible interfacing with various logic families and pull-up configurations.
- Wide single-supply voltage operation capability supporting systems ranging from low-voltage to high-voltage environments.
Applications
- General-purpose signal comparison in industrial control systems
- Voltage monitoring and threshold detection circuits
- Over-voltage protection mechanisms
Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND) before finalizing procurement plans. Confirm that the MSOP-8 package dimensions align with existing PCB footprints. Ensure compliance with RoHS directives if required by specific project standards. Check for alternative sourcing options due to potential end-of-life constraints associated with this lifecycle stage.
Selection Notes
Select this component when a dual-channel comparator with low input offset voltage and wide supply voltage tolerance is required. Consider the open collector output requirement for interface compatibility. Evaluate the thermal performance within the specified -40°C to +105°C range against environmental conditions. Assess power consumption needs relative to the 600 µA supply current specification.
Part Context
This part belongs to the BA2903xx series of analog comparators from ROHM Semiconductor. It shares functional similarities with other members like the BA2903SFVM-TR but differs in packaging and specific parameter tolerances. The series is characterized by standard ground-sense capabilities and robust electrostatic protection features common to ROHM's comparator lineup.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer datasheets for direct pin-compatible alternatives or evaluate generic dual comparators with similar electrical specifications.
