BU7445SHFV-TR

Overview

The BU7445SHFV-TR is a low-power ground-sense operational amplifier manufactured by ROHM Semiconductor. It operates on a single supply voltage ranging from 1.7 V to 5.5 V, with a typical circuit current of 0.04 mA per channel. The device features ground detection input capability and full-amplitude output swing, extending from VSS+0.1 V to VDD-0.1 V. Key electrical specifications include a maximum input offset voltage of 6 mV, a typical gain-bandwidth product of 0.4 MHz, and an input bias current of 0.001 nA. It is housed in a compact HVSOF5 package measuring 1.6x1.6 mm.

Feature Summary

• Ground-sense input architecture allows operation down to the negative supply rail
• Full-amplitude output swing capability for maximum dynamic range
• Integrated phase compensation capacitors simplify circuit design
• Ultra-low power consumption suitable for battery-operated applications

Applications

• Portable electronic devices requiring extended battery life
• Battery-powered sensor interfaces
• Low-voltage signal conditioning circuits
• Consumer electronics with strict power constraints

Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity requirements directly with the manufacturer or authorized distributors. Confirm RoHS compliance status and ensure the component meets the required operating temperature range for the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when ground-referenced input signals are required alongside low power consumption. The ground-sense feature distinguishes it from standard rail-to-rail amplifiers that may not accept inputs at the negative rail. Ensure the application does not require automotive qualification, as this series is not recommended for such use.

Part Context

This part belongs to the BU74xx series of low-power CMOS operational amplifiers from ROHM Semiconductor. The series is characterized by its ability to operate at very low voltages while maintaining high input impedance and low bias currents. It is designed for general-purpose analog signal processing in portable and battery-driven systems.

Replacement Considerations

No official substitute part numbers are confirmed in the provided documentation. Consult the manufacturer's datasheet for potential cross-reference options if availability is constrained.
