BU7266FV-E2

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.

Instrumentation, Op Amps, Buffer Amps 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.
