BA3472YFVM-CTR

Overview

The BA3472YFVM-CTR is a high-speed ground sense operational amplifier manufactured by ROHM Semiconductor. It features two channels in an 8-MSOP package and is AEC-Q100 qualified for automotive applications. The device operates on a single supply voltage ranging from 3 V to 36 V, with a typical circuit current of 4 mA per channel. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 10 V/µs, and a voltage gain of 100 dB. Input offset voltage is typically 10 mV, while input bias current is 100 nA. The output can source up to 30 mA per channel, and the common-mode rejection ratio is 97 dB.

Feature Summary

• High-speed operation with a 10 V/µs slew rate and 4 MHz gain-bandwidth product
• Ground sense capability allowing input voltage range down to the negative supply rail
• Automotive grade qualification compliant with AEC-Q100 standards
• Wide operating temperature range suitable for harsh environments

Applications

• Automotive sensor signal conditioning
• Current sensing circuits
• Industrial control systems requiring high-speed amplification

Procurement Notes

Verify the specific suffix CTR indicates tape and reel packaging when ordering. Confirm that this component is marked as Not Recommended for New Designs (NRND) in official documentation before finalizing any new product development plans. Ensure compatibility with existing design constraints due to potential future obsolescence.

Selection Notes

Select this component when high-speed performance and ground-sense input are required in automotive or industrial environments. Compare against standard op-amps if lower bandwidth suffices, but prioritize this part for applications demanding fast transient response. Verify power supply requirements align with the 3 V to 36 V operating range.

Part Context

This part belongs to the BA3472 series of high-speed operational amplifiers from ROHM Semiconductor. It shares functional similarities with other ground-sense amplifiers but is distinguished by its specific automotive qualification and speed characteristics. The MSOP8 package offers a compact footprint for space-constrained designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the ROHM portfolio that may be currently recommended for new designs. Evaluate generic high-speed op-amps only if they meet the exact ground-sense and automotive qualification requirements.
