BU7294FV-E2

Overview

The BU7294FV-E2 is a four-channel CMOS operational amplifier manufactured by ROHM Semiconductor, housed in an SSOP-B14 package. It features a gain-bandwidth product of 2.8 MHz and a slew rate of 3 V/µs. The device operates on a supply voltage ranging from 2.4 V to 5.5 V with a typical quiescent current of 0.5 mA per channel. Key electrical specifications include a maximum input offset voltage of 9 mV, an input bias current of 1 pA, and an output current capability of 8 mA. It supports full-swing input and output operation within the supply rails.

Feature Summary

• Supports full-swing input and output voltage ranges extending close to the power supply rails.
• Delivers high-speed performance with a 3 V/µs slew rate and 2.8 MHz gain-bandwidth product.
• Maintains low power consumption with a typical operating current of 0.5 mA per channel.

Applications

• General-purpose signal amplification in portable electronic devices
• Sensor interface circuits requiring low input bias current
• Battery-powered systems utilizing single-supply operation

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm compliance with RoHS directives and material declarations. Confirm that the SSOP-B14 package dimensions match your PCB footprint requirements. Ensure the operating temperature range of -40°C to +85°C aligns with your system's environmental conditions before finalizing procurement.

Selection Notes

Select this component when full-signal swing is required at both input and output nodes within a low-voltage environment. The 1 pA input bias current makes it suitable for high-impedance sensor applications where leakage must be minimized. Compare its 2.8 MHz bandwidth against higher-speed alternatives if signal fidelity at elevated frequencies is critical for your design.

Part Context

This part belongs to the BU729x series of CMOS operational amplifiers designed for low-voltage, low-power applications. The series emphasizes rail-to-rail capabilities and high speed relative to its power consumption profile. It serves as a standard-grade solution for consumer electronics and industrial control systems requiring multi-channel amplification.

Replacement Considerations

Consult official substitution guides for compatible quad-channel op-amps with similar GBW and supply voltage ranges. Verify pin compatibility and thermal characteristics before replacing the original component in existing designs.
