BU7275HFV-TR

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations
