TDA8920TH/N1,118

Overview

The TDA8920TH is a high-efficiency Class-D audio power amplifier by NXP Semiconductors, housed in an HSOP24 package. It delivers up to 2 x 80 W in stereo single-ended mode or mono bridge-tied load configurations. Operating on a supply voltage range of ±12.5 V to ±30 V, it features differential inputs and internal protections including over-temperature, short-circuit, and undervoltage shutdown. The device includes a built-in oscillator with external clock capability and ensures low distortion with minimal quiescent current consumption.

Feature Summary

• High efficiency Class-D architecture with very low dissipation
• Differential audio inputs for high common-mode rejection
• Integrated protection against over-temperature, short-circuits, and supply anomalies
• Configurable as stereo single-ended or mono bridge-tied load amplifier

Applications

• Television sets
• Home-sound systems
• Multimedia systems
• Mains-fed audio equipment
• Car audio boosters

Procurement Notes

Verify the specific suffix (N1,118) against the manufacturer's latest documentation to confirm packaging and environmental compliance details. As this component may be subject to lifecycle changes, check current availability status directly with authorized distributors or NXP Semiconductors before finalizing procurement plans.

Selection Notes

Select this amplifier for applications requiring high output power within a compact form factor. Ensure the design accommodates the required heatsinking based on ambient temperature and thermal resistance calculations. Verify that the power supply rails remain within the ±12.5 V to ±30 V operating range to maintain proper functionality and protection activation.

Part Context

This component belongs to the TDA8920 series of Class-D power amplifiers designed by Philips/NXP Semiconductors. It represents a single-chip solution integrating power switches, drivers, and control logic. The HSOP24 package facilitates surface-mount installation while providing adequate thermal management through an exposed pad for heat dissipation.

Replacement Considerations

Check for direct pin-compatible alternatives within the TDA892x family, such as the TDA8920B or TDA8920C, ensuring their respective datasheets confirm identical electrical characteristics and pinout compatibility for your specific application requirements.
