BU7255SHFV-TR

Overview

The BU7255SHFV-TR is a single-channel, low-voltage, high-speed CMOS operational amplifier manufactured by ROHM Semiconductor. It features a gain-bandwidth product of 4 MHz and a slew rate of 3.4 V/µs. The device operates within a supply voltage range of 2.4 V to 5.5 V with a typical operating current of 540 µA. Key electrical parameters include an input offset voltage of 1 mV, input bias current of 1 pA, output current capability of 4 mA per channel, common-mode rejection ratio of 40 dB, and power supply rejection ratio of 45 dB. It is housed in a compact HVSOF-5 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrates phase compensation capacitor on a single chip for full-swing output operation.
• Designed for low-voltage applications with ultra-low input bias current characteristics.
• Provides high-speed performance suitable for demanding signal processing tasks.

Applications

• Low voltage signal conditioning circuits
• High-speed analog signal processing
• Portable electronic devices requiring efficient power management

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to integration. Ensure the HVSOF-5 footprint matches the target PCB layout constraints. Validate that the operating temperature range meets the environmental requirements of the final assembly.

Selection Notes

Select this component for designs requiring a balance between speed and power efficiency in single-supply systems. The 1 pA input bias current makes it suitable for high-impedance sensor interfaces. Compare the 4 MHz bandwidth against application signal frequencies to ensure adequate response time. Consider the 540 µA quiescent current impact on total system battery life compared to lower-power alternatives.

Part Context

This part belongs to the BU7255 series of low-voltage high-speed CMOS operational amplifiers. The series is characterized by monolithic integration and full-swing output capabilities. It is distinct from other ROHM op-amps like the BU7295, which offers different bandwidth and current specifications. The SHFV variant specifically denotes the HVSOF-5 package configuration.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult official ROHM documentation for direct replacements or cross-reference similar single-channel CMOS op-amps with matching HVSOF-5 packages and comparable electrical specifications.
