BU7265SG-TR

Overview

The BU7265SG-TR is a single-channel CMOS operational amplifier from ROHM Semiconductor, designed for ultra-low power applications. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical circuit current of 0.35 µA per channel. The device features input and output full-swing capabilities, allowing operation close to the supply rails. Key electrical parameters include a gain-bandwidth product of 4 kHz, a slew rate of 2.4 V/µs, and an input bias current of 1 pA. It is housed in a compact SSOP-5 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Ultra-low power consumption with typical current draw of 0.35 µA
• Input and output full-swing operation across the supply voltage range
• Wide operating temperature range suitable for industrial environments
• Integrated phase compensation capacitor for stability

Applications

• Battery-powered portable devices
• Sensor signal amplification
• Low-power instrumentation circuits

Procurement Notes

Verify the specific suffix 'SG' indicates the extended temperature grade (+105°C) compared to standard variants. Confirm RoHS compliance status through official datasheets or manufacturer declarations. Ensure the SSOP-5 package dimensions match your PCB footprint requirements. Check for any automotive qualification restrictions as this is a standard-grade product not recommended for vehicle use.

Selection Notes

Select this component when minimizing quiescent current is critical while maintaining rail-to-rail input and output swing. The wide temperature range makes it suitable for harsh environments. Compare against other BU72xx series members if higher speed or different packaging is required. Ensure the low bandwidth (4 kHz) meets the signal frequency requirements of the application.

Part Context

This part belongs to the BU7265 family of ultra-low power CMOS operational amplifiers. It shares core specifications with the BU7265G but offers an extended industrial temperature range. The family is designed for battery-operated equipment where power efficiency and full-signal swing are prioritized over high-speed performance.

Replacement Considerations

Direct pin-compatible substitutes may exist within the same ROHM BU72xx series, such as the BU7265G for commercial temperature grades. Cross-manufacturer replacements require verification of supply voltage, current consumption, and package compatibility.
