BA3472WFV-CE2

Overview

The BA3472WFV-CE2 is a dual-channel high-speed operational amplifier designed for automotive applications, qualified under AEC-Q100 standards. It operates within a wide single-supply voltage range of 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 10 V/µs, and a typical circuit current consumption of 2 mA per channel. The device features a maximum input offset voltage of 7.5 mV, an input bias current of 100 nA, and a voltage gain of 100 dB. It supports output currents up to 30 mA and functions reliably across an operating temperature range from -40°C to +125°C.

Feature Summary

• Integrated dual-channel architecture with built-in phase compensation capacitors for stable operation without external components.
• Wide supply voltage capability supporting both single and dual power configurations for flexible system integration.
• Automotive-grade qualification ensuring reliability in harsh environmental conditions and high-temperature operations.

Applications

• Engine control units requiring high-speed signal processing
• Electric power steering systems needing precise amplification
• Anti-lock braking systems demanding fast transient response

Procurement Notes

Verify the component status before procurement as this part is marked as not recommended for new designs. Confirm that existing inventory meets functional requirements for legacy systems. Ensure compatibility with SSOP-B8 packaging specifications during integration. Check for alternative qualified parts if long-term supply assurance is required for ongoing production cycles.

Selection Notes

Select this component when designing circuits that require dual-channel amplification within a compact SSOP-B8 package. Consider its 4 MHz bandwidth and 10 V/µs slew rate for applications needing moderate speed performance. Evaluate the 3 V to 36 V operating range against available power rails. Verify thermal management capabilities given the 125°C maximum junction temperature rating.

Part Context

This device belongs to ROHM's automotive high-speed operational amplifier series, specifically engineered for robust performance in vehicle electronics. It shares architectural similarities with other BA347x family members but offers distinct dual-channel configuration. The CE2 suffix indicates specific automotive qualification and packaging variations compared to standard industrial variants.

Replacement Considerations

BA3472FVT-C is a related variant within the same product family offering similar electrical characteristics. Verify pinout compatibility and package dimensions before substitution. Ensure replacement parts meet the same AEC-Q100 automotive grade requirements for critical applications.
