BU7266FV-E2

Overview

The BU7266FV-E2 is a low-power, input-output full-swing operational amplifier manufactured by ROHM Semiconductor. It features two channels within an SSOP-B8 package. The device operates on a single power supply ranging from 1.8 V to 5.5 V. Key electrical specifications include a gain-bandwidth product of 4 kHz and a slew rate of 2.4 V/µs. Input bias current is typically 1 pA, with an input offset voltage of 1 mV. The operating temperature range extends from -40°C to +85°C.

Feature Summary

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

Applications

• Battery-powered portable electronic devices
• Sensor signal amplification circuits
• Low-voltage analog signal processing

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest documentation to confirm compliance status and pinout configuration. Ensure the SSOP-B8 package dimensions match the target PCB footprint requirements. Confirm that the 1.8 V minimum supply voltage aligns with the system's power architecture before finalizing procurement.

Selection Notes

Select this component when ultra-low quiescent current is critical alongside rail-to-rail output performance. It serves as a suitable alternative to higher-speed op-amps in low-frequency applications where power efficiency outweighs bandwidth requirements. Verify that the 4 kHz gain-bandwidth product meets the signal frequency needs of the specific circuit design.

Part Context

This part belongs to the BU7266 series of CMOS operational amplifiers designed for low-voltage operation. The series emphasizes minimal power draw while maintaining full output swing capabilities. It is distinct from high-speed variants like the BU7486 series, focusing instead on efficiency for portable and sensor-based systems.

Replacement Considerations

Check for direct pin-compatible alternatives within the same ROHM family or cross-reference with other low-power, dual-channel op-amps offering similar 1.8 V to 5.5 V operation and full-swing outputs if sourcing constraints exist.
