BU7245HFV-TR

Overview

The BU7245HFV-TR is a single-channel, low-power CMOS operational amplifier manufactured by Rohm Semiconductor. It features rail-to-rail input and output capabilities within a supply voltage range of 1.8 V to 5.5 V. The device exhibits an ultra-low supply current of 5 µA and a typical input bias current of 1 pA. Key electrical parameters include a gain-bandwidth product of 70 kHz, a slew rate of 0.035 V/µs, and an output current capability of 8 mA. It operates across a temperature range of -40°C to +85°C and is housed in a compact 5-HVSOF package.

Feature Summary

• Ultra-low power consumption with 5 µA supply current for battery-operated applications
• Rail-to-rail input and output operation across the full supply voltage range
• High input impedance characterized by 1 pA typical input bias current
• Integrated electrostatic protection circuitry for enhanced reliability

Applications

• Portable electronic devices requiring extended battery life
• Battery-powered sensor signal conditioning circuits
• Low-voltage analog signal processing systems
• General-purpose amplification in consumer electronics

Procurement Notes

Verify the specific suffix TR indicates tape and reel packaging configuration when sourcing. Confirm RoHS compliance status aligns with project requirements. Ensure the 5-HVSOF footprint matches the target PCB layout dimensions. Validate that the operating temperature range meets environmental specifications. Check for any specific handling instructions related to the surface-mount package type.

Selection Notes

Select this component for designs prioritizing minimal quiescent current over high-speed performance. The 70 kHz bandwidth limits suitability for high-frequency signal processing. Compare against higher-speed variants like the BU7255 if slew rate requirements exceed 0.035 V/µs. Consider the 8 mA output drive capability for load matching. Evaluate the 5-HVSOF package size constraints against available board space.

Part Context

This part belongs to the BU7245 series of low-power operational amplifiers from Rohm. The series includes variants such as the BU7245HFV (tube) and other speed grades within the family. These components are designed for general-purpose use in low-voltage environments. The HVSOF package provides a small form factor suitable for dense PCB layouts.

Replacement Considerations

The BU7245HFV is the non-tape variant of the same device. No direct cross-manufacturer substitutes are confirmed in the provided documentation.
