BA3472YF-LBH2

Overview

The BA3472YF-LBH2 is a dual-channel high-speed operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3 V to 36 V and draws an operating supply current of 4 mA. Key electrical specifications include a gain-bandwidth product of 4 MHz, a slew rate of 10 V/us, and a voltage gain of 100 dB. The device features a common-mode rejection ratio of 97 dB, an input bias current of 100 nA, and an input offset voltage of 10 mV. Each channel provides an output current capability of 30 mA. It is housed in an 8-SOP package and is qualified under AEC-Q100 standards for automotive applications.

Feature Summary

• Dual-channel architecture designed for high-speed signal processing applications
• Automotive-grade qualification ensuring reliability in demanding environments
• High output drive capability supporting loads requiring up to 30 mA per channel

Applications

• Automotive sensor signal conditioning circuits
• Industrial data acquisition systems
• General-purpose amplification in automotive electronics

Procurement Notes

Verify the specific suffix LBH2 against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure compatibility with existing board layouts due to the 8-SOP form factor. Confirm AEC-Q100 qualification status if the application requires automotive grade components. Check for end-of-life notices or recommended replacement parts as availability may vary.

Selection Notes

Select this component when a dual-channel op-amp with moderate bandwidth (4 MHz) and high slew rate (10 V/us) is required. It is suitable for designs needing a wide single-supply voltage range from 3 V to 36 V. Consider the 100 nA input bias current and 10 mV offset voltage for precision requirements. The AEC-Q100 qualification makes it appropriate for automotive use cases where robustness is critical.

Part Context

This part belongs to ROHM's family of high-speed operational amplifiers. The BA3472 series typically offers dual-channel configurations optimized for speed and drive strength. The BA3472YF-LBH2 variant specifically denotes the automotive-qualified version with the corresponding package and tape-and-reel configuration. It serves as a solution for applications requiring reliable analog signal amplification in vehicle systems.

Replacement Considerations

Check for direct cross-reference models from ROHM or other manufacturers offering identical 4 MHz GBP and 10 V/us slew rates in an 8-SOP package. Verify that any substitute maintains the same AEC-Q100 qualification and 3-36 V operating voltage range. Ensure pin-to-pin compatibility before replacing.
