TDA1519C/N3S,112

Overview

The TDA1519C/N3S,112 is a B-class audio amplifier integrated circuit manufactured by NXP USA Inc. It supports mono or stereo output configurations in a 20-HSOP package. The device operates on a supply voltage ranging from 6V to 17.5V and delivers up to 22W into a 4-ohm load for single-channel operation, or 11W per channel into a 2-ohm load for stereo operation. It functions within a junction temperature range of -25°C to 150°C.

Feature Summary

• Integrated protection mechanisms including pop-noise elimination, mute functionality, short-circuit protection, thermal shutdown, and standby mode.

Applications

• Audio amplification in consumer electronic devices requiring high power output
• Car audio systems utilizing B-class amplifier topology
• Home entertainment equipment with mono or stereo audio requirements

Procurement Notes

Verify the exact part number suffix against official NXP documentation, as variations such as /N3,112 may indicate specific packaging or tape-and-reel configurations. Confirm RoHS compliance status and current product lifecycle stage, as this component may be subject to discontinuation notices. Ensure the supplier provides valid traceability documents matching the manufacturer's specifications.

Selection Notes

Select this component when designing audio circuits that require robust B-class amplification with built-in protection features. Consider the 20-HSOP package constraints for surface-mount assembly and verify that the system's power supply can maintain stability within the 6V to 17.5V operating range. Evaluate thermal management requirements given the high junction temperature tolerance and potential power dissipation at maximum output levels.

Part Context

This component belongs to the TDA151 series of audio amplifiers from NXP. It is designed for applications demanding reliable audio performance with integrated safety features. The device represents a solution for driving speakers efficiently while minimizing external component count through internal protection and control logic integration.

Replacement Considerations

Consult NXP official documentation for confirmed substitute part numbers. Verify pin compatibility and electrical specifications before replacing any existing components in a design.
