BU7487SF-E2

Overview

The BU7487SF-E2 is a four-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, featuring a gain-bandwidth product of 10 MHz and a slew rate of 10 V/µs. The device exhibits an input offset voltage of 1 mV and an input bias current of 1 pA. It delivers an output current of 8 mA per channel with a typical circuit current of 6 mA. Packaged in an SSOP-14 format, it supports operation from -40°C to +105°C.

Feature Summary

Ground sense input capability allowing detection at the negative rail
Full amplitude output swing extending close to the supply rails
High-speed performance with wide bandwidth and fast slew rate
Low power consumption suitable for portable battery-operated equipment

Applications

Portable electronic devices requiring low voltage operation
Sensor signal conditioning circuits
Battery-powered instrumentation systems
General-purpose analog signal processing in compact designs

Procurement Notes

Verify the specific suffix E2 against the official manufacturer datasheet to confirm compliance with RoHS directives and lead-free status. Ensure the SSOP-14 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when ground-referenced input signals are required without level shifting. The four-channel configuration reduces board space compared to single or dual-channel alternatives. Verify that the 10 MHz bandwidth meets the signal frequency requirements of the specific application design.

Part Context

This part belongs to the BU748x series of CMOS operational amplifiers designed for low voltage applications. It shares architectural similarities with the BU7486 and BU7485 variants but offers four independent channels. The series is optimized for cost-effective solutions in consumer electronics where power efficiency and signal integrity are critical.

Replacement Considerations

Consult the official ROHM replacement guide for verified substitutes. Direct pin-compatible alternatives may include other members of the BU748x family if channel count differs. Cross-reference specifications carefully to ensure equivalent speed and voltage characteristics.
