TPA3111D1PWPR Product Features:

The TPA3111D1PWPR integrates numerous advanced features, delivering outstanding performance and reliability:

High Efficiency and Low Thermal Dissipation: The Class D architecture achieves high efficiency (>90%10), eliminating the need for external heat sinks during music playback. This makes it particularly suitable for space-constrained and portable devices.

Superior Audio Performance: Delivers low distortion (low THD+N) and high signal-to-noise ratio (SNR) audio output. The differential input structure helps suppress common-mode noise, enhancing immunity to interference.

Comprehensive Protection Mechanisms: Incorporates built-in thermal protection (Thermal Protection), automatically shutting down output when the chip junction temperature exceeds safe limits; short-circuit protection (against output-to-ground, output-to-supply, and output-to-output shorts), with an auto-recovery feature enabling the amplifier to resume normal operation once fault conditions are resolved.

Wide supply voltage range (8V to 26V): Enables flexible deployment across scenarios powered by batteries, adapters, or other power sources.

Low quiescent current: Contributes to extended battery life in portable devices.

TPA3111D1PWPR Application Areas:

With its features, the TPA3111D1PWPR is ideally suited for the following applications:

Televisions and Monitors: The integrated SpeakerGuard™ function effectively protects television speaker units, while its high efficiency and space-saving package offer distinct advantages.

Laptops and Portable Audio Devices: High efficiency contributes to extended battery life, and the compact package suits space-constrained designs.

Bluetooth speakers and portable audio systems: High output power and battery-friendly operation make it a popular choice for portable wireless speakers.

Car audio auxiliary systems: Its wide input voltage range offers some adaptability to automotive power environments, though selection of automotive-grade chip variants is essential to meet stringent requirements.

Smart home audio products: Suitable for smart speakers, smart displays, and other home devices requiring audio playback functionality.
