BU7266SF-E2

Overview

The BU7266SF-E2 is a dual-channel ultra-low power CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.8 V to 5.5 V and features input-output full-swing capabilities. 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. The device draws a typical circuit current of 350 µA per channel and provides an output current of 2.4 mA. It is housed in an SOP-8 package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Ultra-low power consumption suitable for battery-driven applications
• Input-output full-swing operation across the supply voltage range
• Low input bias current for high impedance signal interfacing

Applications

• Battery-powered portable devices
• Sensor signal amplification
• Portable electronic equipment

Procurement Notes

Verify the specific suffix E2 against the manufacturer's official datasheet to confirm pinout compatibility and environmental compliance status. Ensure the SOP-8 package dimensions match the target PCB footprint requirements. Confirm that the extended industrial temperature range meets the operational environment specifications before finalizing procurement orders.

Selection Notes

Select this component when low quiescent current is critical alongside rail-to-rail output requirements. The 4 kHz bandwidth limits suitability for high-frequency signal processing but supports precision DC or low-frequency AC applications. Consider the 1 pA input bias current for high-impedance sensor interfaces where leakage currents must be minimized.

Part Context

This part belongs to the BU7266 series of ultra-low power CMOS operational amplifiers. It shares architectural similarities with the BU7265 series but offers dual-channel integration in an SOP-8 package. The device is designed as a standard-grade component for general-purpose low-power analog signal conditioning tasks.
