TDA1519CTD/N3C,118

Overview

The TDA1519CTD/N3C,118 is a Class-B dual output power amplifier in a 20-lead heatsink small outline package (HSOP20). It delivers up to 22 W in Bridge-Tied Load (BTL) configuration or 2 x 11 W in stereo mode. The device operates with a supply voltage range of 6 V to 17.5 V and features fixed gain, low offset voltage, and integrated mute/standby functionality.

Feature Summary

• Supports both stereo and BTL configurations with minimal external components
• Integrated mute and standby switch for low current consumption
• Protected against AC/DC short circuits, thermal overload, and reverse polarity
• Eliminates switch-on/off plops and handles high energy on outputs

Applications

• Automotive audio systems
• Home entertainment equipment
• Portable hi-fi applications

Procurement Notes

Verify the specific ordering suffix N3C,118 against official documentation to confirm material composition and environmental compliance status. Ensure the HSOP20 package variant matches the required thermal management strategy for the target application environment.

Selection Notes

Select this component for designs requiring high output power from a single IC with simple biasing. The fixed 40 dB gain simplifies circuit design. Consider the thermal resistance characteristics when designing the PCB copper area for heat dissipation in enclosed spaces.

Part Context

This part belongs to the TDA1519 family of power amplifiers. It is pin-compatible with the TDA1519B and TDA1519CSP variants. The CTD designation specifically indicates the 20-lead HSOP package with the heatsink facing the PCB for soldered mounting.
