Amplifier IC 2-Channel (Stereo) Class D 28-HTSSOP
NRND23,649 in stock

Overview

The TPA3110D2PWPR is a high-efficiency Class-D stereo audio power amplifier capable of driving speakers up to 15W per channel into an 8-ohm load. Operating from a wide supply voltage of 8V to 26V, it features advanced SpeakerGuard technology including an adjustable power limiter and DC protection to prevent speaker damage. Its filter-free design and high efficiency of up to 90 percent eliminate the need for an external heat sink when playing music.

Why Choose This Part

The TPA3110D2PWPR offers four selectable, fixed gain settings and differential inputs for high noise rejection in complex PCB layouts. Its flow-through pinout simplifies routing and reduces parasitic effects, while the integrated self-protection circuitry ensures reliability against thermal overloads and pin-to-pin shorts.

Applications

Television and Monitor Audio
Integrated stereo speakers in flat-panel displays requiring compact, thermally efficient amplification.
Wireless and Bluetooth Speakers
Portable audio systems leveraging the high efficiency to extend battery life and reduce thermal footprint.
Public Address Systems
Energy-efficient distributed audio and announcement systems with robust short-circuit protection.
Computer Speakers
High-quality desktop audio requiring low THD+N and pop-free startup and shutdown performance.

Getting Started

To evaluate the IC, use the TPA3110D2EVM evaluation module which provides a reference layout for thermal management and filter-free operation. When designing your PCB, ensure the thermal pad of the 28-HTSSOP package is soldered to a large ground plane to maximize power dissipation. Consult the datasheet for calculating the PLIMIT resistor value to set the maximum output voltage swing for your specific speakers.
