TDA8932T/N1,112

Overview

The TDA8932T/N1,112 is a high-efficiency Class-D audio amplifier manufactured by NXP Semiconductors. It features two full-differential inputs driving independent outputs, supporting stereo half-bridge or mono full-bridge configurations. The device delivers typical output power of 2x15 W in stereo mode with a 4 Ω load and 2x30 W in full-bridge mode with an 8 Ω load. Operating within a supply voltage range of 10 V to 36 V, it incorporates thermal foldback to maintain performance without external heat sinks under standard music playback conditions.

Feature Summary

• High efficiency Class-D architecture designed for low power dissipation
• Dual full-differential inputs enabling flexible mono or stereo bridge configurations
• Integrated thermal foldback protection for reliable operation without external heatsinks
• Supports continuous output power through proper printed-circuit board cooling

Applications

• Stereo half-bridge audio systems requiring 2x15 W output
• Mono full-bridge applications delivering up to 2x30 W into 8 Ω loads
• Consumer electronics utilizing efficient Class-D amplification
• Audio designs requiring differential input signal processing

Procurement Notes

Verify component authenticity through authorized distributors as the part status is discontinued. Confirm package integrity and pin alignment against the 32-SO specification before integration. Review datasheet revisions for any historical parameter updates. Ensure compliance with RoHS and REACH standards relevant to the manufacturing batch date.

Selection Notes

Select this component for designs requiring dual-channel Class-D amplification with differential inputs. Evaluate thermal management requirements based on the specific load impedance and supply voltage. Consider the discontinuation status when planning long-term production lifecycles. Verify compatibility with existing PCB footprints for the 32-SOP package.
