BU7242F-E2

Overview

The BU7242F-E2 is a low voltage CMOS operational amplifier manufactured by ROHM Semiconductor. It features two channels in an SOP-8 package, operating within a supply voltage range of 1.8 V to 5.5 V. Key electrical parameters include a gain-bandwidth product of 900 kHz, a slew rate of 400 mV/µs, and a maximum input offset voltage of 1 mV. The device draws 180 µA of quiescent current per channel and provides a typical output current of 10 mA. It supports full-swing input and output operation with an internal phase compensation capacitor.

Feature Summary

• Supports low voltage single-supply operation from 1.8 V to 5.5 V
• Enables full-amplitude input and output voltage swing capabilities
• Integrates internal phase compensation capacitors for stability
• Features extremely low input bias current characteristics

Applications

• Low voltage signal conditioning circuits
• Battery-powered portable electronic devices
• General-purpose analog signal processing
• Sensor interface applications requiring high input impedance

Procurement Notes

Verify the specific suffix E2 against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the SOP-8 package dimensions match the target PCB footprint requirements. Confirm RoHS compliance status through the latest official documentation before finalizing procurement decisions.

Selection Notes

Select this component when designing systems requiring low power consumption alongside full-signal swing capabilities at reduced supply voltages. The integrated phase compensation simplifies circuit design by eliminating external components. Consider the 1 pA input bias current for high-impedance sensor interfaces where leakage currents must be minimized.

Part Context

This part belongs to the BU7242F series of low-power, full-swing operational amplifiers. The series is characterized by CMOS technology optimized for low-voltage applications. The device integrates multiple functions on a single chip, offering a compact solution for analog signal processing tasks in space-constrained designs.

Replacement Considerations

Check for direct substitutes within the same ROHM family or equivalent general-purpose op-amps with matching pinouts and electrical characteristics. Verify that alternative components support the required 1.8 V minimum supply voltage and full-swing output requirements.
