BU7294SFV-E2

Overview

The BU7294SFV-E2 is a four-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It features high-speed input-output full swing capabilities with a gain-bandwidth product of 2.8 MHz and a slew rate of 3 V/µs. 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 specifications 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 an SSOP-14 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• High-speed operation with full swing input and output voltage ranges.
• Low power consumption suitable for battery-operated applications.
• Extended industrial temperature range capability.
• Ultra-low input bias current for precision signal handling.

Applications

• Portable electronic devices requiring low voltage operation
• Sensor interface circuits
• General-purpose analog signal processing

Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm compliance with RoHS directives and lead-free manufacturing standards. Ensure the SSOP-14 package dimensions match the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the part number with official ROHM documentation to avoid counterfeit components.

Selection Notes

Select this component when a quad-channel amplifier with rail-to-rail output swing is required under low voltage conditions. The 2.8 MHz bandwidth and 3 V/µs slew rate support moderate speed applications. Consider the 1 pA input bias current for high-impedance sensor interfaces. The wide temperature range makes it suitable for industrial environments where standard commercial grade parts may fail.

Part Context

This part belongs to the BU7294Sxx series of CMOS operational amplifiers designed for high-speed and low-voltage applications. The series emphasizes full-swing input/output performance while maintaining low power consumption. The BU7294SFV-E2 variant specifically denotes the SSOP-14 package configuration with extended temperature ratings, distinguishing it from other package options within the same functional family.

Replacement Considerations

The BU7294SF-E2 is a related variant offering identical electrical characteristics but utilizes an SOP-14 package instead of SSOP-14. Verify pin compatibility and physical footprint differences before substitution. No other direct substitutes are confirmed in the provided data.
