BU7264F-E2

Overview

The BU7264F-E2 is a four-channel low-voltage CMOS operational amplifier manufactured by ROHM Semiconductor. It features high-speed input-output full swing capabilities with a gain-bandwidth product of 2 MHz and a slew rate of 1.1 V/us. The device operates on a single power supply ranging from 1.8 V to 5.5 V, consuming 1.1 mA of operating current. Key electrical specifications include an input offset voltage of 1 mV, input bias current of 1 pA, output current of 10 mA per channel, CMRR of 45 dB, and PSRR of 60 dB. It is housed in an SOP-8 surface-mount package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Supports full-swing input and output voltage ranges across the entire supply rail.
• Integrates internal phase compensation capacitors for simplified circuit design.
• Maintains extremely low input bias current characteristics typical of CMOS technology.

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 datasheet to confirm pinout compatibility and electrical tolerances. Ensure the SOP-8 package dimensions match the target PCB footprint. Confirm that the operating temperature range of -40°C to +85°C meets the environmental requirements of the final assembly. Cross-reference the RoHS status with local regulatory standards before integration.

Selection Notes

Select this component when full-signal swing is required at both input and output nodes under low-voltage conditions. The 2 MHz bandwidth suits moderate-speed applications where power efficiency is prioritized over high-frequency performance. Compare against other BU726x variants if different channel counts or package styles are needed for space-constrained designs.

Part Context

This part belongs to the BU726x series of full-swing operational amplifiers designed for low-voltage operation. The series includes single, dual, and quad configurations sharing similar electrical architectures. The BU7264F-E2 specifically provides four channels in an SOP-8 package, distinguishing it from higher-pin-count variants like the BU7264SF which uses SOP-14.
