Overview

The TAS5613ADKDR is a high-performance Class D power amplifier designed to drive loudspeakers with up to 300W in mono (2 Ohm) or 200W per channel in stereo (3 Ohm) configurations. It operates from a wide supply voltage range of 18V to 38V, utilizing an integrated feedback design that ensures low distortion and high audio quality. The device features a thermally enhanced 44-pin HSSOP package with an exposed pad for efficient heat dissipation.

Why Choose This Part

The TAS5613ADKDR offers excellent thermal management through its HSSOP package and integrated protection circuitry, including short-circuit and thermal shutdown. Its differential inputs help reject common-mode noise, while the depop feature minimizes audible transients during power-up and power-down cycles.

Applications

Home Theater Systems
High-power output stages for multi-channel AV receivers and surround sound systems.
Active Subwoofers
Driving low-impedance subwoofer drivers with high current capability in PBTL mono mode.
Professional Audio Speakers
Integrated amplification for powered studio monitors and compact PA systems.
Mini Combo Systems
Space-constrained stereo systems requiring high efficiency and minimal heatsink requirements.

Getting Started

Designers should prioritize low-ESR decoupling capacitors placed close to the VDD pins and follow TI's recommended PCB layout for the exposed thermal pad. Evaluation can be performed using the TAS5613PHD2EVM or similar PurePath Digital reference designs. Ensure the system controller manages the shutdown and reset pins correctly to sequence the power stage.
