BA15218N

Overview

The BA15218N is a monolithic integrated circuit containing two low-noise, low-distortion operational amplifiers with internal phase compensation. It supports single power supplies from 4V to 32V or dual supplies from ±3V to ±16V. Key electrical characteristics include a typical input offset voltage of 0.5mV, quiescent current of 8mA, and gain-bandwidth product of 10MHz. The device features a slew rate of 3V/ms and high open-loop voltage gain of 110dB.

Feature Summary

• Low noise level operation suitable for audio applications
• High slew rate and wide bandwidth performance
• Compatible with standard dual operational amplifier pin connections

Applications

• Audio signal processing circuits
• RIAA equalization networks
• General-purpose analog signal conditioning

Procurement Notes

Verify the specific package type matches the required footprint, as the N suffix denotes an 8-pin SIP package distinct from DIP or SOP variants. Confirm supply voltage limits align with system requirements before integration. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when low distortion and high gain are prioritized over ultra-low power consumption. The 8mA quiescent current is higher than modern CMOS alternatives but supports robust output drive capabilities. Ensure the thermal dissipation capacity of the SIP package meets the ambient temperature conditions of the target application environment.

Part Context

This part belongs to the BA15218 series, which includes BA15218 (DIP) and BA15218F (SOP) variants. All three share identical electrical specifications and functionality, differing only in physical packaging. The series is designed as a drop-in replacement for industry-standard dual op-amps like the NE5532 and TL082 families.

Replacement Considerations

The datasheet explicitly states compatibility with 4558 and 4560 models regarding pin connections. Verify that substitute components maintain similar slew rates and noise figures for critical audio paths.
