TDA8932BT/N2,112

Overview

The TDA8932BT/N2,112 is a Class-D audio amplifier manufactured by NXP Semiconductors. It delivers 2 × 15 W in stereo half-bridge (RL = 4 Ω) or 1 × 30 W in mono full-bridge (RL = 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 operates without an external heat sink during music playback. It includes two full-differential inputs, switchable internal/external oscillator, and protection against short circuits, overtemperature, and undervoltage.

Feature Summary

High efficiency Class-D architecture with low power dissipation
Integrated thermal foldback for operation without external heat sinks
Full differential inputs supporting mono BTL or stereo SE configurations
Comprehensive protection including thermal foldback, current limiting, and short-circuit proofing

Applications

Flat panel television sets
Flat panel monitor sets
Multimedia systems
Wireless speakers
Mini and micro systems

Procurement Notes

Verify the specific ordering suffix /N2,112 corresponds to the SO32 plastic small outline package variant. Confirm component status as discontinued before design finalization. Ensure supply chain sources provide valid RoHS compliance documentation. Cross-reference pinout requirements for the 32-lead package against the target PCB layout.

Selection Notes

Select this component for applications requiring high output power with minimal thermal management. Verify that the load impedance matches the specified bridge configuration for optimal performance. Ensure the power supply range aligns with the 10 V to 36 V asymmetrical specification. Consider the master-slave oscillator synchronization if multiple units are deployed in a single system.

Part Context

This part belongs to the TDA8932B family of Class-D audio amplifiers. It is designed for high-efficiency audio reproduction in consumer electronics. The device integrates DMOS transistors and PWM modulation circuitry. It supports both mono bridged-tied load and stereo single-ended topologies within a single integrated circuit.
