BU7495HFV-TR

Overview

The BU7495HFV-TR is a high-speed, ground-sense operational amplifier manufactured by ROHM Semiconductor. It features a single circuit configuration housed in a compact 5-HVSOF surface-mount package. The device operates on a low voltage supply ranging from 1.8 V to 5.5 V with a typical supply current of 650 µA. Key electrical characteristics include a gain-bandwidth product of 4 kHz, a slew rate of 5 V/µs, and an input bias current of 1 pA. It supports full-swing output operation within a temperature range of -40°C to 85°C.

Feature Summary

• Ground-sense input capability allowing operation down to the negative rail
• High-speed CMOS architecture for rapid signal response
• Full-swing output stage maximizing dynamic range at low voltages
• Ultra-low input bias current for high-impedance source applications

Applications

• Battery-powered portable electronic devices requiring low voltage operation
• Sensor signal conditioning circuits with ground-referenced inputs
• Industrial control systems utilizing single-supply configurations
• Automotive infotainment and body electronics (non-critical safety)
• Medical instrumentation requiring low power consumption

Procurement Notes

Verify the specific suffix and packaging format against the official manufacturer datasheet before ordering. Confirm that the component meets all environmental compliance requirements such as RoHS standards for your intended application region. Ensure that the storage and handling conditions adhere to the moisture sensitivity level specified in the official documentation to prevent damage during assembly.

Selection Notes

Select this component when a single-supply, ground-sense operational amplifier is required for low-voltage applications. It is suitable for designs needing full-swing output capabilities without external biasing networks. Consider the trade-off between the moderate gain-bandwidth product and the ultra-low input bias current when evaluating performance for precision analog signal processing tasks.
