BA15218F

Overview

The BA15218F is a dual operational amplifier in an 8-pin SOP package. It supports single power supplies from 4V to 32V and dual supplies from ±3V to ±16V. Key electrical parameters include a typical input offset voltage of 0.5mV, quiescent current of 5mA, and high-amplitude voltage gain of 110dB. The device features a slew rate of 3V/ms and a gain-bandwidth product of 10MHz. Input conversion noise is typically 1.0mVrms (RIAA). Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Low-noise performance with low distortion characteristics
• High slew rate and wide bandwidth for signal fidelity
• Compatible with standard dual operational amplifier pin connections

Applications

• Audio visual equipment
• Office-automation equipment
• Communications devices
• Electrical appliances

Procurement Notes

Verify the specific ordering suffix against official ROHM documentation to confirm package type and tape/reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Confirm that the intended application falls within ordinary electronic equipment limits, as safety-critical uses require direct consultation with the manufacturer.

Selection Notes

Select this component when a dual op-amp with low noise and high slew rate is required. It serves as a drop-in replacement for standard dual operational amplifiers like the 4558 and 4560 models due to identical pin connections. Consider the 8-pin SOP package for surface-mount assembly needs.

Part Context

This part belongs to the BA15218 family, which includes DIP and SIP variants. It is designed for general-purpose analog signal processing where low distortion and high gain are prioritized. The internal phase compensation simplifies circuit design by ensuring stability without external components.

Replacement Considerations

The datasheet notes compatibility with 4558 and 4560 models based on pin connections. Verify electrical parameter overlaps before substitution.
