BU7264SF-E2

Overview

The BU7264SF-E2 is a four-channel low-voltage CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.8 V to 5.5 V, consuming 1.1 mA of operating current. Key electrical specifications include a gain-bandwidth product of 2 MHz, a slew rate of 1.1 V/µs, and an input offset voltage of 1 mV. The device features a typical input bias current of 1 pA and delivers 10 mA output current per channel. It provides a common-mode rejection ratio of 45 dB and a power supply rejection ratio of 60 dB. The component is housed in a SOP-14 surface-mount package and supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Supports full-swing input and output operation across the entire supply voltage range.
• Integrates internal phase compensation capacitors for simplified circuit design.
• Features extremely low input bias current characteristics suitable for high-impedance applications.

Applications

• Low voltage signal conditioning circuits
• Portable battery-powered electronic devices
• General-purpose analog signal processing

Procurement Notes

Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SOP-14 package dimensions match the target PCB footprint. Confirm that the application does not require automotive qualification, as this standard-grade part is explicitly noted as unsuitable for vehicle equipment.

Selection Notes

Select this component when a quad-channel amplifier with rail-to-rail capabilities is required under single-supply conditions. It is appropriate for designs prioritizing low quiescent current and wide temperature stability. Consider alternative packages like SSOP if space constraints differ from the SOP-14 form factor.

Part Context

This device belongs to the BU7264SF series of full-swing operational amplifiers. It represents a monolithic integration of four amplifier channels with built-in phase compensation. The series is designed to replace older bipolar op-amps in low-voltage systems, offering improved power efficiency and wider input/output voltage swings compared to traditional counterparts.

Replacement Considerations

The BU7264SFV-E2 serves as a direct functional substitute utilizing an SSOP-14 package instead of SOP-14. Other members of the BU7264 family may offer different channel counts or package styles but share similar electrical characteristics.
