BU7486FVM-TR

Overview

The BU7486FVM-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 3V to 5.5V and supports an extended industrial temperature range from -40°C to +105°C. Key electrical characteristics include a typical gain-bandwidth product of 10MHz, a slew rate of 10V/µs, and a maximum input offset voltage of 9.5mV. The device features rail-to-rail output capability and ultra-low input bias current, packaged in an 8-pin MSOP format with a standard reel quantity of 3000 units.

Feature Summary

• Ground-sense input capability allowing signal detection down to the negative supply rail
• High-speed performance with wide bandwidth and fast slew rate for dynamic applications
• Low voltage operation suitable for portable and battery-powered systems
• Rail-to-rail output swing maximizing dynamic range in single-supply configurations

Applications

• Portable electronic devices requiring low power consumption and high speed
• Sensor signal conditioning circuits with ground-referenced inputs
• Battery-operated instrumentation and measurement equipment
• Video signal processing and buffering applications
• Active filter designs in compact consumer electronics

Procurement Notes

Verify the specific suffix and package variant against the official manufacturer datasheet before ordering. Confirm that the intended application environment remains within the specified operating temperature limits. Ensure compatibility with the required supply voltage constraints. Check for any recent lifecycle status updates or recommended replacement parts directly from the manufacturer's official documentation.

Selection Notes

Select this component when ground-sense input is required alongside high-speed signal processing in low-voltage environments. Compare the 10MHz bandwidth and 10V/µs slew rate against system requirements. Consider the 8-pin MSOP package for space-constrained designs. Evaluate the trade-off between the higher speed of this model and lower power alternatives if energy efficiency is the primary constraint.

Part Context

This part belongs to the BU7486 series of CMOS operational amplifiers designed for general-purpose high-speed applications. It shares architectural similarities with other members of the family but offers specific performance metrics tailored for ground-sense operations. The series is distinct from lower-power variants like the BU7462, offering higher bandwidth at the cost of increased quiescent current.

Replacement Considerations

Consult the official manufacturer datasheet for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before considering alternative models. Do not assume functional interchangeability with other series without explicit manufacturer validation.
