Overview
The BA2904YFV-CE2 is a dual-channel automotive-grade operational amplifier manufactured by ROHM Semiconductor. It features a gain-bandwidth product of 500 kHz and a slew rate of 200 mV/us. The input offset voltage is 2 mV, with an input bias current of 20 nA. Operating on a single supply from 3 V to 36 V or dual supplies up to ±18 V, it consumes 500 uA of quiescent current. Each channel provides 30 mA output current and achieves a common-mode rejection ratio of 65 dB. The device is housed in an SSOP-B8 package and operates within a temperature range of -40°C to +125°C.
Feature Summary
- Ground-sense input capability allowing operation near the negative rail
- Automotive qualification compliant with AEC-Q100 standards
- Low power consumption suitable for battery-operated systems
Applications
- Engine control units
- Anti-lock braking systems
- Electric power steering systems
Procurement Notes
Verify component authenticity through authorized channels due to the NRND status. Confirm package integrity upon receipt as the device utilizes surface-mount technology. Ensure storage conditions align with manufacturer specifications to maintain reliability. Cross-reference datasheet revisions to confirm pinout compatibility before integration into existing designs.
Selection Notes
Select this component for applications requiring ground-referenced signal processing in automotive environments. Consider the 500 kHz bandwidth for low-frequency sensing tasks. Evaluate thermal management requirements given the SSOP-B8 package constraints. Verify that the 30 mA output drive capability meets load requirements without external buffering.
Part Context
This part belongs to ROHM's BA2904 series of ground-sense operational amplifiers designed for automotive use. It integrates two independent amplifiers in a compact SSOP-B8 package. The series supports wide voltage ranges and offers high reliability under harsh operating conditions typical of vehicle electronics.
Replacement Considerations
Check for direct pin-compatible substitutes such as LM2904 variants if available. Verify electrical parameter equivalence including gain-bandwidth and offset voltage. Confirm package dimensions match existing PCB footprints. Review functional safety documentation if used in safety-critical circuits.
