Overview
The BA3474WFV-CE2 is a four-channel high-speed operational amplifier manufactured by ROHM Semiconductor, designed for automotive applications. It operates within a supply voltage range of 3 V to 36 V and features a gain-bandwidth product of 4 MHz with a slew rate of 10 V/µs. The device delivers a typical voltage gain of 100 dB and a common-mode rejection ratio of 97 dB. Each channel provides an output current of 30 mA with an input bias current of 150 nA and an input offset voltage of 7.5 mV. It functions reliably across a temperature range of -40°C to +125°C and is housed in an SSOP-B14 package.
Feature Summary
- Four independent high-speed operational amplifier channels integrated on a single chip
- Wide operating power supply voltage range supporting single or dual power sources
- Ground sense capability allowing common-mode input voltage range to include ground level
- Qualified for automotive use under AEC-Q100 standards
Applications
- Engine control units
- Electric power steering systems
- Anti-lock braking systems
Procurement Notes
Verify the component status before procurement as it is marked NRND (Not Recommended for New Designs). Confirm that existing inventory meets functional requirements for legacy projects. Ensure compatibility with SSOP-B14 footprints during board design reviews. Check RoHS compliance documentation if required by specific regional regulations. Validate that the AEC-Q100 qualification aligns with target automotive grade specifications.
Selection Notes
Select this component when a quad-channel configuration is required for space-constrained automotive designs. Consider its 30 mA output drive capability for moderate load applications. Evaluate the 4 MHz bandwidth against signal frequency requirements to ensure adequate performance. Compare the 10 V/µs slew rate with dynamic signal handling needs. Verify that the wide supply voltage range matches the system's power architecture.
Part Context
This part belongs to ROHM's automotive-grade high-speed operational amplifier family. It shares architectural similarities with other members like the BA3472 series but offers four channels instead of two. The device is engineered to meet stringent automotive reliability standards while providing high-speed signal processing capabilities essential for modern vehicle control systems.
Replacement Considerations
The BA3474RFV-E2 is a related variant within the same product line. Both are classified as NRND. Direct pin-compatible substitutes from other manufacturers require careful verification of electrical parameters and automotive qualification status.
