BU7475SHFV-TR

Overview

The BU7475SHFV-TR is a single-channel, low-power CMOS operational amplifier manufactured by ROHM Semiconductor. It features a gain-bandwidth product of 100 kHz and a slew rate of 0.05 V/µs. The device operates within a supply voltage range of 1.7 V to 5.5 V with a typical supply current of 9 µA. Key electrical specifications include an input offset voltage of 1 mV, an input bias current of 1 pA, and an output current capability of 14 mA per channel. It is housed in a compact 5-HVSOF package.

Feature Summary

• Ultra-low power consumption suitable for battery-driven applications
• Ground-sense input capability allowing operation down to the negative rail
• Full-swing output design maximizing dynamic range at low voltages

Applications

• Portable consumer electronics requiring extended battery life
• Battery-powered sensor signal conditioning circuits
• Low-voltage analog signal processing in mobile devices
• Precision instrumentation powered by single-cell or dual-cell batteries

Procurement Notes

Verify the specific suffix SHFV against official manufacturer documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with surface-mount assembly processes for the HVSOF-5 footprint. Cross-reference the part number with the latest ROHM datasheet to validate environmental compliance and operating temperature ranges before integration.

Selection Notes

Select this component when designing low-voltage systems that require ground-referenced inputs without sacrificing output swing. The ultra-low quiescent current makes it ideal for energy-constrained portable devices. Compare its 100 kHz bandwidth against higher-speed alternatives if signal fidelity requirements exceed standard audio or slow sensor frequencies.

Part Context

This device belongs to the BU74xx series of low-power operational amplifiers from ROHM Semiconductor. The series is characterized by CMOS technology optimized for minimal current draw while maintaining stable performance across a wide temperature range. It serves as a specialized solution for applications where power efficiency and rail-to-rail functionality are critical constraints.

Replacement Considerations

Consult official ROHM documentation for confirmed substitute part numbers. Do not assume functional equivalence with other series members without verifying pinout and electrical parameter alignment.
