TDF8544AJ/N2,112

Overview

The TDF8544AJ/N2,112 is a quad-channel Class AB audio amplifier manufactured by NXP USA Inc. It features BTL output configuration and operates within a supply voltage range of 6V to 18V. The device is housed in a 27-pin DBS27P SIP package with formed leads for through-hole mounting. Designed for high-performance audio applications, it integrates protection mechanisms including thermal shutdown and short-circuit protection.

Feature Summary

• Quad-channel BTL Class AB architecture
• Integrated thermal and short-circuit protection
• Through-hole SIP-27 packaging

Applications

• Multi-speaker audio systems
• Home theater amplifiers
• Professional audio equipment

Procurement Notes

Verify component authenticity and datasheet revisions before integration. Confirm RoHS compliance status and lead-free specifications against current regulatory requirements. Check for obsolete status or lifecycle changes as availability may be restricted. Ensure proper handling procedures for the SIP package during assembly.

Selection Notes

Select this component for designs requiring four independent audio channels in a single package. The BTL topology supports higher power delivery compared to standard configurations. Verify that the system supply voltage remains within the specified 6V to 18V range. Ensure adequate thermal management solutions are implemented due to the SIP package characteristics.

Part Context

This part belongs to the TDF8544 series of audio amplifiers from NXP Semiconductors. It shares architectural similarities with other members like the TDF8544J but may differ in specific suffix designations or regional manufacturing variations. The series targets high-fidelity audio reproduction with integrated protection features.

Replacement Considerations

Direct substitutes include TDF8544J/N2,112 and TDF8544J/N3,112. Verify pin compatibility and electrical parameters before substitution. Cross-reference datasheets to ensure identical functionality and package dimensions.
