BU7464F-E2

Overview

The BU7464F-E2 is a high-speed, ground-sense operational amplifier manufactured by ROHM Semiconductor. It integrates four voltage-feedback amplifiers with built-in phase compensation capacitors on a single chip. The device operates on a single power supply ranging from 1.7 V to 5.5 V, featuring low current consumption and minimal input bias current. It supports an operating temperature range of -40°C to +85°C and is housed in a 14-pin SOP package.

Feature Summary

• Ground sense input capability allowing signal detection down to the negative supply rail
• Full amplitude output swing extending close to both positive and negative supply rails
• Integrated phase compensation capacitors eliminating external component requirements
• Low voltage operation with ultra-low input bias current characteristics

Applications

• Battery-powered portable electronic devices requiring extended runtime
• Single-supply sensor signal conditioning circuits
• Audio pre-amplification stages in consumer electronics
• Industrial control systems utilizing low-voltage logic interfaces

Procurement Notes

Verify the specific suffix E2 for lead-free compliance and RoHS status against official manufacturer documentation. Confirm package dimensions and pinout compatibility during integration planning. Ensure sourcing channels provide authentic components with traceable manufacturing data.

Selection Notes

Select this component when designing single-supply systems requiring input signals near ground potential. The integrated compensation simplifies layout compared to uncompensated variants. Evaluate the 1 MHz gain-bandwidth product against required signal frequencies to ensure adequate performance margins.

Part Context

This part belongs to the BU7464 series of CMOS operational amplifiers designed for low-voltage applications. It represents a quad-channel configuration within ROHM's portfolio of general-purpose analog signal processing ICs suitable for cost-sensitive consumer and industrial markets.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalent parts. Cross-reference electrical specifications such as gain-bandwidth product and supply voltage ranges before implementing any alternative components.
