BU7262SF-E2

Overview

The BU7262SF-E2 is a dual-channel CMOS operational amplifier manufactured by ROHM Semiconductor. It operates within a supply voltage range of 1.8 V to 5.5 V and consumes a typical quiescent current of 550 µA. The device features a gain-bandwidth product of 2 MHz and a slew rate of 1.1 V/µs. Input offset voltage is specified at a maximum of 1 mV, with an input bias current of 1 pA. Each channel provides an output current capability of 10 mA. Common-mode rejection ratio is rated at 45 dB, while power supply rejection ratio reaches 60 dB. It functions in temperatures from -40°C to +105°C and is housed in an 8-SOP package.

Feature Summary

• Low voltage operation supporting single-supply systems down to 1.8 V
• CMOS architecture enabling low power consumption suitable for battery-driven applications
• Rail-to-rail output swing capability maximizing dynamic range
• High input impedance with minimal bias current for precision signal conditioning

Applications

• Portable electronic devices requiring extended battery life
• Sensor signal amplification circuits
• Low voltage analog signal processing
• Battery-powered instrumentation

Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm compliance with RoHS directives and lead-free status. Ensure the SOP-8 package dimensions match the target PCB footprint. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the ordering code with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a dual-channel amplifier is required for low-voltage environments below 3.3 V or 5 V standards. The 2 MHz bandwidth suits moderate-speed applications rather than high-frequency RF tasks. Consider the 10 mA output drive if interfacing with low-impedance loads. Evaluate the 1 mV offset voltage specification against the system's accuracy requirements for DC-coupled signals.

Part Context
