Procurement Notes

Verify the specific ordering suffix and package variant against the official manufacturer datasheet before procurement. Confirm that the selected component meets the required industrial or commercial temperature ratings for the intended application environment. Ensure compliance with RoHS directives and other relevant regulatory standards applicable to the final product assembly.

Selection Notes

Select this component when designing circuits that require rail-to-rail output swing with inputs capable of reaching the negative supply rail. Consider the 10 MHz bandwidth and 10 V/µs slew rate for moderate-speed signal conditioning tasks. Evaluate the low quiescent current and small SSOP-B8 package size for space-constrained, battery-operated designs where precision and speed are balanced requirements.

Part Context

This device belongs to the BU7486 series of CMOS operational amplifiers designed for low-voltage, high-speed applications. It shares architectural similarities with the BU7485 and BU7487 series but offers a dual-channel configuration optimized for cost-sensitive and space-efficient designs. The series is widely utilized in consumer electronics and portable equipment where power efficiency and signal integrity are critical design parameters.

Replacement Considerations

Consult the official ROHM Semiconductor replacement guide for verified alternative part numbers. Ensure any substitute component matches the pinout, electrical characteristics, and package dimensions of the BU7486FV-E2 to maintain circuit compatibility without redesign.
