Overview
The BA2903SFVM-TR is a dual-channel analog comparator manufactured by ROHM Semiconductor, housed in an 8-pin MSOP surface-mount package. It operates on a single supply voltage ranging from 2V to 36V or dual supplies of ±1V to ±18V. The device features open-collector outputs capable of sourcing up to 16mA per channel and draws a typical operating current of 600µA. Key electrical specifications include a maximum input offset voltage of 7mV, a typical response time of 1.3µs, and a wide operating temperature range from -40°C to +125°C.
Feature Summary
- Supports operation with both single and dual power supplies across a wide voltage range.
- Features open-collector outputs that allow compatibility with various logic families.
- Includes built-in electrostatic protection circuits for enhanced reliability.
Applications
- General-purpose voltage level detection
- Threshold monitoring circuits
- Over-voltage protection systems
Procurement Notes
Verify the component status as Not Recommended for New Designs (NRND) before integration into new products. Confirm the specific suffix matches the required tape-and-reel packaging format. Ensure compliance with RoHS directives and check for any updated lifecycle notices from the manufacturer prior to final procurement decisions.
Selection Notes
Select this component when a low-cost, general-purpose dual comparator is required for applications involving moderate speed and standard precision. Consider the open-collector output structure for interfacing with different voltage domains. Evaluate the thermal performance within the specified operating temperature range to ensure long-term stability in the target environment.
Part Context
This part belongs to the BA2903xx series of analog comparators from ROHM Semiconductor. It is designed as a cost-effective solution for basic comparison tasks. The MSOP-8 package provides a compact footprint suitable for space-constrained printed circuit board layouts while maintaining standard pin configurations for ease of design implementation.
Replacement Considerations
LM2903FVM-TR is listed as a manufacturer-recommended substitute.
