BU7205SHFV-TR

Overview

The BU7205SHFV-TR is a single-channel, low-power input-output full swing operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical circuit current of 400 nA per channel. Key electrical parameters include a gain-bandwidth product of 2.5 kHz, a slew rate of 2.5 V/µs, and an input offset voltage of 1 mV. The device features an extremely low input bias current of 1 pA and supports output currents up to 1.2 mA. It provides a common-mode rejection ratio of 45 dB and a power supply rejection ratio of 60 dB. The component is housed in a compact HVSOF-5 surface-mount package and functions reliably across an extended temperature range from -40°C to +105°C.

Feature Summary

• Ultra-low supply current consumption suitable for battery-powered applications
• Full input and output voltage swing capability
• Extremely low input bias current for high-impedance signal interfacing

Applications

• Portable electronic devices requiring minimal power draw
• Battery-operated instrumentation systems
• Low-voltage sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix SHFV against the manufacturer's official datasheet to confirm pinout compatibility and thermal characteristics. Ensure the ordering quantity aligns with the standard reel packaging requirements specified by ROHM. Cross-reference the RoHS compliance status with current regulatory standards for your target market before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that demand both ultra-low quiescent current and rail-to-rail signal handling capabilities. It is appropriate for applications where the input signal approaches the supply rails and where minimizing power consumption is critical. Consider the 2.5 kHz bandwidth limitation when evaluating suitability for higher-frequency signal processing tasks compared to faster operational amplifiers.

Part Context

This part belongs to the BU7205 series of low-power CMOS operational amplifiers from ROHM. The series is characterized by its ability to operate at very low voltages while maintaining full input and output voltage swings. It is designed as a monolithic IC integrating phase compensation capacitors, making it self-stable without external components. The family targets portable and battery-driven equipment where energy efficiency is paramount.

Replacement Considerations

Consult the official ROHM documentation for direct cross-references. Verify that any substitute maintains the HVSOF-5 package dimensions and electrical specifications such as the 1.8 V minimum operating voltage and 400 nA current consumption.
