BU7486SFVM-TR

Overview

The BU7486SFVM-TR is a dual-channel, ground-sense, high-speed, low-voltage CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 3 V to 5.5 V and features a typical gain-bandwidth product of 10 MHz with a slew rate of 10 V/µs. The device supports an output current of 8 mA per channel and maintains a low input bias current of 0.001 nA. Packaged in an MSOP-8 format, it functions reliably across an extended temperature range from -40 °C to +105 °C.

Feature Summary

• Ground sense input capability allowing operation down to the negative supply rail
• High-speed performance with wide bandwidth and fast slew rate for signal integrity
• Low voltage operation suitable for portable and battery-powered applications
• Ultra-low input bias current ensuring minimal loading on high-impedance sources

Applications

• Portable electronic devices requiring efficient power management
• Sensor signal conditioning circuits for accurate data acquisition
• Battery-operated instrumentation systems
• Low-voltage analog signal processing modules

Procurement Notes

Verify the specific suffix and package variant against the official manufacturer datasheet before ordering. Confirm that the MSOP-8 tape and reel configuration matches the production requirements. Ensure compliance with RoHS standards and check for any automotive or industrial qualification restrictions if applicable to the end-use environment.

Selection Notes

Select this component when ground-referenced input signals are required without level shifting. It is appropriate for designs needing high speed within a single low-voltage supply constraint. Compare specifications against similar series members like the BU7485 or BU7487 to ensure the dual-channel configuration and specific electrical parameters align with the circuit design goals.

Part Context

This part belongs to the BU7486S series of CMOS operational amplifiers designed for ground sensing applications. It shares architectural similarities with the BU7485G and BU7487x families but offers specific performance characteristics tailored for low-voltage, high-speed environments. The series is intended for general-purpose use in consumer electronics rather than automotive-grade applications.

Replacement Considerations

Consult the official ROHM documentation for confirmed substitute part numbers. Direct replacements may include other members of the BU7486 family or compatible ground-sense amplifiers from the same manufacturer. Verify pinout compatibility and electrical parameter equivalence before implementing any substitution.
