TDA8932BTW/N2,112

Overview

The TDA8932BTW/N2,112 is a Class-D audio amplifier by NXP Semiconductors in a 32-lead HTSSOP package. It delivers 2x15 W stereo (4 Ω) or 1x30 W mono BTL (8 Ω). Operating voltage ranges from 10 V to 36 V asymmetrical or ±5 V to ±18 V symmetrical. The device features thermal foldback and full protection circuits, enabling heat sink-free operation during music playback.

Feature Summary

• Supports mono full-bridge (BTL) and stereo half-bridge (SE) configurations with fully differential inputs for high common-mode rejection.
• Integrates comprehensive protection mechanisms including thermal foldback, overcurrent limiting, and supply voltage monitoring to prevent damage.
• Features switchable internal or external oscillators for master-slave synchronization across multiple devices.

Applications

• Flat panel television sets
• Flat panel monitor sets
• Multimedia systems

Procurement Notes

Verify the exact ordering suffix against official documentation, as variations exist between bulk and tape-and-reel packaging. Confirm RoHS compliance status and lead-free soldering specifications prior to integration. Ensure the specific variant matches the required application constraints and regulatory standards.

Selection Notes

Select this component for designs requiring high efficiency and low power dissipation without external heatsinks. Consider the thermal resistance characteristics of the HTSSOP32 package and verify that the PCB copper area provides adequate heat sinking for the intended power levels.

Part Context

This part belongs to the TDA8932B family of Class-D amplifiers. It utilizes a thermally enhanced thin shrink small outline package designed for efficient heat dissipation. The device integrates DMOS output transistors and control logic into a single compact solution.
