Overview
The BA3474YFV-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 3 MHz with a slew rate of 8.5 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 a maximum input bias current of 150 nA and an input offset voltage of 1 mV. It functions reliably across a temperature range of -40°C to +125°C in an SSOP-B14 package.
Feature Summary
- Features EMARMOUR technology for excellent electromagnetic interference (EMI) characteristics suitable for automotive environments.
- Supports ground sensing with a common-mode input voltage range extending to the negative supply rail.
- Complies with AEC-Q100 standards for automotive grade reliability.
Applications
- Automotive sensor signal conditioning
- Engine control unit circuits
- Body control module interfaces
Procurement Notes
Verify component authenticity through authorized channels as this part carries an NRND status. Confirm that the specific suffix matches required automotive qualification levels. Check for updated lifecycle notices before finalizing procurement plans due to potential obsolescence risks associated with non-recommended designs.
Selection Notes
Select this component when EMI immunity is critical for high-speed amplification in noisy automotive environments. Ensure the design accommodates the SSOP-B14 package dimensions and thermal dissipation requirements. Verify that the 3 MHz bandwidth meets system signal processing needs without requiring higher-frequency alternatives.
Part Context
This device belongs to ROHM's automotive-grade high-speed operational amplifier family. It shares functional similarities with other BA34xx series parts but distinguishes itself through integrated EMI protection technologies. The four-channel configuration allows for compact multi-sensor interface solutions in space-constrained automotive electronic control units.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult manufacturer resources for direct replacements or evaluate alternative ROHM automotive op-amps with comparable EMI specifications and pin compatibility.
