TDA1519B/N2,112

Overview

The TDA1519B/N2,112 is a Class-B dual output audio power amplifier designed for car radio applications. It operates within a supply voltage range of 6.0 V to 18.0 V and delivers up to 6 W per channel in stereo mode or 12 W in Bridge-Tied Load (BTL) configuration. The device features fixed gain, low offset voltage, and integrated protection against short circuits, thermal overload, and reverse polarity.

Feature Summary

• Integrated mute and stand-by switch functionality with low current consumption
• Built-in load dump protection and AC/DC short-circuit safety
• Low DC output offset voltage optimized for BTL operation
• High energy handling capability at outputs

Applications

• Car radio power amplification
• Stereo audio systems
• Bridge-Tied Load (BTL) speaker configurations

Procurement Notes

Verify the specific ordering suffix /N2,112 against manufacturer documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status as datasheets may vary by production batch. Ensure the component matches the 9-lead SIL plastic package outline SOT110B before integration into the design.

Selection Notes

Select this component for automotive audio designs requiring high output power with minimal external components. The fixed gain simplifies circuit design compared to variable gain alternatives. Consider the 9-lead SIL package constraints for PCB layout and thermal dissipation requirements when choosing between stereo and BTL modes.

Part Context

This part belongs to the TDA1519 series of audio amplifiers developed primarily for automotive use. It is compatible with the TDA1519A, though output power ratings differ. The device represents a medium-power solution utilizing a single in-line package suitable for direct mounting on printed circuit boards.

Replacement Considerations

The TDA1519A is documented as compatible regarding function, but offers different output power characteristics. Verify pinout and thermal performance before substitution.
