BU7266SFV-E2

Overview

The BU7266SFV-E2 is a two-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It features ultra-low power consumption with a typical circuit current of 0.35 mA per channel. The device supports a supply voltage range from 1.8 V to 5.5 V and operates within an extended temperature range of -40°C to +105°C. Key electrical specifications include a gain-bandwidth product of 4 kHz, a slew rate of 0.0024 V/µs, and an input bias current of 1 pA. It provides full swing output capability ranging from VSS+0.1 V to VDD-0.1 V.

Feature Summary

• Ultra-low power consumption suitable for battery-driven applications
• Input-output full swing operation extending close to supply rails
• Extended industrial operating temperature range up to 105°C

Applications

• Battery-powered portable electronic devices
• Sensor signal amplification circuits
• Low-power analog signal conditioning

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm compliance with current environmental standards and pinout configurations. Ensure the SSOP-B8 package dimensions match the target PCB footprint requirements. Confirm that the extended temperature rating aligns with the system's thermal design constraints before finalizing procurement.

Selection Notes

Select this component when designing systems requiring minimal quiescent current alongside rail-to-rail output performance. It is appropriate for applications where high speed is not critical but low power draw and wide supply voltage flexibility are primary design drivers. Consider the limited slew rate when evaluating suitability for dynamic signal processing tasks.

Part Context

This part belongs to the BU7266 series of low-consumption, input-output full swing operational amplifiers. The series includes variants such as the BU7266FV-E2 and BU7266SF, which share similar core functionalities but may differ in package types or specific temperature ratings. The BU7266SFV-E2 specifically denotes the SSOP-B8 package variant within this family.

Replacement Considerations

Direct substitutes include other members of the BU7266 series such as the BU7266FV-E2, provided the package type difference between SSOP-B8 and SOIC-8 is accommodated in the design.
