BA3472YF-CGE2

Overview

The BA3472YF-CGE2 is a dual-channel high-speed operational amplifier manufactured by ROHM Semiconductor, designed for automotive applications with AEC-Q100 qualification. It operates within a supply voltage range of 3 V to 36 V and supports temperatures from -40°C to +125°C. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 10 V/µs, and a typical voltage gain of 100 dB. The device features a common-mode rejection ratio (CMRR) of 97 dB and a power supply rejection ratio (PSRR) of 97 dB. Each channel provides an output current capability of 30 mA, with a maximum input offset voltage of 10 mV and an input bias current of 100 nA. The component is housed in an 8-SOP surface-mount package.

Feature Summary

• Automotive-grade reliability certified under AEC-Q100 standards for harsh environment operation
• High-speed performance characterized by a 4 MHz gain-bandwidth product and 10 V/µs slew rate
• Wide single-supply operating voltage range extending up to 36 V
• Integrated phase compensation capacitor eliminating external frequency compensation requirements

Applications

• Engine control units requiring high-voltage signal processing
• Electric power steering systems utilizing differential amplification
• Anti-lock braking system sensor interfaces

Procurement Notes

Verify the specific suffix CE2 or CGE2 against the manufacturer's latest datasheet to ensure correct packaging and tape-and-reel specifications. Confirm that the NRND status does not impact long-term availability for existing production lines. Check RoHS compliance documentation for environmental regulatory adherence. Validate pinout compatibility if replacing legacy components in established designs.

Selection Notes

Select this component when designing circuits requiring wide dynamic voltage ranges up to 36 V in a compact SOP-8 footprint. The high slew rate and bandwidth make it suitable for fast transient response applications. Ensure thermal management accounts for the specified power dissipation limits at maximum operating temperatures. Consider the input bias current characteristics for high-impedance source applications.

Part Context

This part belongs to the BA3472 series of high-speed operational amplifiers developed for automotive electronics. It shares functional similarities with other members like the BA3472WFV-CE2 but differs in package type, offering the SOP-8 form factor for surface-mount assembly. The series is engineered to meet the rigorous demands of vehicle control systems while maintaining standard op-amp terminal connections.

Replacement Considerations

BA3472YF-C is the non-lead-free variant of this component family.
