BA2904YFVM-CTR

Overview

The BA2904YFVM-CTR is a dual-channel standard ground sense operational amplifier manufactured by ROHM Semiconductor. It operates within a wide power supply voltage range of +3.0V to +36.0V (single supply) or ±1.5V to ±18.0V (dual supply). The device features a typical gain-bandwidth product of 0.5 MHz and a slew rate of 0.2 V/µs. Key electrical characteristics include a maximum input offset voltage of 3.5 mV, typical input bias current of 20 nA, and output short-circuit protection with a typical output current capability of 30 mA per channel. It supports an operating temperature range from -40°C to +125°C.

Feature Summary

• Standard ground sense input configuration allowing operation down to the negative supply rail.
• Wide single-supply operating voltage range supporting low-voltage to high-voltage applications.
• Automotive-grade qualification compliant with AEC-Q100 standards for reliability.
• Low quiescent current consumption suitable for battery-powered systems.

Applications

• Engine control units in automotive environments
• Electronic Power Steering (EPS) systems
• Anti-lock Braking Systems (ABS)
• Industrial sensor signal conditioning

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific suffix matches the required tape-and-reel packaging format. Ensure compliance with RoHS directives and functional safety support categories as defined in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when ground-referenced input signals are required without level shifting. Consider the 0.5 MHz bandwidth limit for high-speed applications. Verify thermal management requirements for the MSOP-8 package under continuous operation at elevated ambient temperatures up to 125°C.

Part Context

This part belongs to the BA2904 series of dual operational amplifiers designed for robust performance in harsh environments. It serves as a specialized variant optimized for automotive electronics, offering enhanced durability compared to standard commercial grade devices while maintaining pin compatibility with legacy designs.

Replacement Considerations

Check for direct cross-reference availability with LM2904 variants if automotive grade is not strictly required. Verify pinout compatibility with existing PCB layouts before substituting with other dual op-amp packages.
