BU7205HFV-TR

Overview

The BU7205HFV-TR is a single-channel CMOS operational amplifier manufactured by Rohm Semiconductor. It features a supply voltage range of 1.8 V to 5.5 V and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a typical supply current of 400 nA, an input bias current of 1 pA, and a gain-bandwidth product of 2.5 kHz. The device offers a slew rate of 0.0025 V/µs, an output current capability of 2 mA, and supports full-swing output operation.

Feature Summary

• Ultra-low power consumption with minimal supply current for battery-driven applications
• Full-swing input and output voltage ranges extending to the supply rails
• High DC voltage gain with low input bias current characteristics
• Integrated electrostatic protection circuitry for enhanced reliability

Applications

• Portable electronic devices requiring extended battery life
• Battery-powered instrumentation systems
• Low-frequency signal conditioning circuits
• Sensor interface amplifiers in consumer electronics

Procurement Notes

Verify the specific suffix HFV-TR against the manufacturer's official datasheet to confirm the HVSOF-5 package type and tape-and-reel packaging configuration. Ensure that the component meets RoHS3 compliance requirements for your target market. Cross-reference the ordering code with authorized distributors to validate authenticity and traceability before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits that prioritize ultra-low quiescent current over high-speed performance. The low gain-bandwidth product makes it suitable for DC or very low-frequency applications rather than audio or RF signals. Consider the full-swing output capability if driving loads close to the supply rails is required within the specified voltage constraints.

Part Context

This part belongs to the BU7205 series of low-power CMOS operational amplifiers from Rohm Semiconductor. The series is designed for portable and battery-operated equipment where minimizing power consumption is critical. The BU7205HFV-TR variant specifically utilizes the HVSOF-5 surface-mount package, offering a compact footprint for space-constrained designs.

Replacement Considerations

Consult official substitution guides for compatible parts within the same family or equivalent low-power op-amps. Verify pin compatibility and electrical parameter alignment before replacing.
