BU7294SF-E2

Overview

The BU7294SF-E2 is a four-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It features high-speed input-output full swing operation with a gain-bandwidth product of 2.8 MHz and a slew rate of 3 V/us. The device operates on a single power supply ranging from 2.4 V to 5.5 V, consuming 2 mA of operating current. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 1 pA, output current of 8 mA per channel, CMRR of 40 dB, and PSRR of 45 dB. It is housed in a SOP-14 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• High-speed input-output full swing capability for wide dynamic signal handling
• CMOS technology enabling low input bias current and low power consumption
• Wide operating temperature range suitable for industrial environments

Applications

• General-purpose analog signal processing circuits
• Industrial control systems requiring wide temperature stability

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Confirm the SOP-14 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power supply rails. Check for any recent design changes or obsolescence notices directly from ROHM Semiconductor before finalizing procurement.

Selection Notes

Select this component when a quad-channel amplifier with high slew rate and full output swing is required under low voltage conditions. It is suitable for applications needing low input bias current and wide temperature tolerance. Compare performance metrics such as GBW and PSRR against alternative quad op-amps if higher precision or lower noise is critical for the specific application design.

Part Context

This part belongs to the BU7294SF series of high-speed, full-swing operational amplifiers. It is designed for general-purpose use in consumer and industrial electronics where low voltage operation and wide bandwidth are necessary. The series emphasizes efficiency through CMOS architecture while maintaining robust performance across varying environmental temperatures.

Replacement Considerations

Consult official substitution guides for compatible quad-channel CMOS op-amps with similar GBP and slew rate specifications. Verify that any substitute matches the SOP-14 package and operating voltage range.
