BU7295SHFV-TR

Overview

The BU7295SHFV-TR is a high-speed, single-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.7 V to 5.5 V and consumes 650 µA of operating current. Key electrical specifications include a gain-bandwidth product of 5 MHz, a slew rate of 5 V/µs, and an open-loop voltage gain of 100 dB. The device features low input bias current (1 pA), input offset voltage of 1 mV, common-mode rejection ratio of 60 dB, and power supply rejection ratio of 80 dB. It supports output currents up to 14 mA per channel and includes internal phase compensation.

Feature Summary

• Operates with full swing input and output voltage ranges across the entire supply voltage spectrum
• Delivers high-speed performance with a 5 MHz gain-bandwidth product and 5 V/µs slew rate
• Maintains extremely low input bias current of 1 pA for minimal signal loading
• Integrates internal phase compensation to ensure stability without external components

Applications

• High-speed signal conditioning circuits requiring wide bandwidth
• Low-voltage portable electronic devices powered by single supplies
• Precision analog front-ends utilizing full-swing input/output capabilities
• Battery-operated systems demanding low quiescent current operation

Procurement Notes

Verify the specific suffix 'SHFV' against official ROHM documentation to confirm package type and tape/reel specifications. Ensure compatibility with HVSOF-5 footprint requirements during PCB layout. Confirm RoHS compliance status through the manufacturer's latest environmental declaration. Validate that the 1.7 V minimum supply voltage aligns with system power rails. Check for any recent lifecycle notifications or obsolescence warnings directly from the supplier.

Selection Notes

Select this component when application requirements demand both high-speed response and low-voltage operation. The 5 MHz bandwidth suits applications needing faster settling times than standard general-purpose amplifiers. The 1 pA input bias current makes it suitable for high-impedance sensor interfaces. Consider the 650 µA supply current if power efficiency is secondary to speed. The HVSOF-5 package offers a compact solution for space-constrained designs.

Part Context

This part belongs to the BU7295 series of high-speed input-output full swing operational amplifiers. It is designed as a monolithic IC integrating a single circuit with built-in phase compensation capacitors. The series emphasizes low voltage operation, low consumption current, and high-speed characteristics. It serves as a specialized alternative to standard op-amps in applications requiring wider dynamic range and faster transient response under low supply voltages.

Replacement Considerations

BU7295HFV-TR is listed as a recommended alternative with similar functionality but different speed characteristics.
