BU7275HFV-TR

Overview

The BU7275HFV-TR is a single-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical quiescent current of 40 µA per channel. Key electrical parameters include a gain-bandwidth product of 600 kHz, a slew rate of 300 mV/µs, and an input bias current of 1 pA. The device supports full-swing input and output operation, with an output current capability of 8 mA. It is housed in a compact HVSOF-5 surface-mount package and functions reliably across an operating temperature range from -40°C to +85°C.

Feature Summary

• Supports low-voltage operation with a wide supply range from 1.8 V to 5.5 V.
• Enables full-amplitude input and output signal swing capabilities.
• Features extremely low input bias current for high-impedance applications.
• Integrates internal phase compensation capacitors to simplify circuit design.

Applications

• Battery-powered portable electronic devices requiring low power consumption
• Signal conditioning circuits in consumer electronics
• Sensor interface amplifiers utilizing high-impedance sources

Procurement Notes

Verify the specific suffix against official ROHM documentation to confirm packaging format and tape specifications. Ensure compatibility with standard surface-mount assembly processes for the HVSOF-5 package. Confirm that the intended application environment remains within the specified commercial temperature limits and does not involve automotive or safety-critical systems, as these are explicitly excluded.

Selection Notes

Select this component when designing low-voltage systems requiring rail-to-rail performance without external compensation components. It is suitable for applications prioritizing minimal static current draw alongside moderate bandwidth requirements. Consider the HVSOF-5 footprint constraints during PCB layout. This part is distinct from higher-speed variants within the family; verify that the 600 kHz bandwidth meets the specific signal frequency needs of the target design.

Part Context

This component belongs to the BU7275 series of low-power, full-swing operational amplifiers. The series integrates multiple configurations, including single, dual, and quad channels, all sharing similar CMOS architecture characteristics. The BU7275HFV-TR specifically denotes the single-channel variant packaged in HVSOF-5 with reel-based taping for automated manufacturing.

Replacement Considerations

BU7275SHFV-TR offers identical electrical specifications but supports an extended maximum operating temperature of +105°C.
