TDA8932T/N1,118

Overview

The TDA8932T/N1,118 is a high-efficiency Class-D audio amplifier manufactured by NXP Semiconductors. It features a single-channel output configuration housed in a 32-pin SOIC package. The device operates within a supply voltage range of 12V to 35V and supports a nominal bandwidth of 20 kHz with a gain of 30 dB. Typical output power reaches 15 W in stereo half-bridge applications with a 4 Ω load or 30 W in full-bridge configurations with an 8 Ω load. It functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• High efficiency Class-D architecture designed for low power dissipation
• Thermal foldback implementation allows operation without external heat sinks under typical music signals
• Two full-differential inputs driving independent outputs for flexible mono or stereo configurations

Applications

• Home theater systems requiring high-power audio amplification
• Active loudspeaker designs utilizing full-bridge configurations
• Portable audio equipment where thermal management is constrained

Procurement Notes

Verify component authenticity through authorized distributors as the part may be discontinued. Confirm package integrity and pin alignment against the 32-SO specification before integration. Review current RoHS compliance status and check for any product change notices affecting manufacturing origin or material composition prior to final procurement decisions.

Selection Notes

Select this component for applications demanding high output power with minimal thermal management requirements. Ensure the design accommodates the 32-pin SOIC footprint and provides adequate PCB cooling paths. Verify that the input signal levels match the differential input specifications and that the supply voltage remains within the 12V to 35V operational limits for stable performance.
