Product Overview
The TAS5611APHDR is TI’s high-power analog-input Class-D audio amplifier SoC built with proprietary PurePath™ HD technology. It combines Class-D high efficiency with Class-AB premium sound quality, supporting two output modes: 2×125W into 4Ω stereo BTL, or 250W mono PBTL into 2Ω loads. Its closed-loop wideband feedback design achieves THD+N below 0.03% and strong PSRR against supply fluctuations. Integrated multi-layer fault protection circuits auto-handle abnormal operating states to secure system stability. Packaged in 14mm×14mm HTQFP-64 with upward exposed thermal pad for direct heatsink mounting, it fits home theater, active subwoofer and professional broadcast sound equipment with continuous high-power operation.
Core Advantages
PurePath™ HD Ultra-High Audio Fidelity
Advanced closed-loop feedback reduces noise and harmonic distortion, delivering transparent high-fidelity audio comparable to high-end linear amplifiers.
High Power Density Output
Provides up to 250W peak mono audio power in compact silicon layout, enabling miniaturized, lightweight audio equipment designs.
High System Energy Efficiency
Over 90% energy conversion efficiency at full power, greatly cutting heat generation and eliminating bulky cooling structures or cooling fans.
Full On-Chip Protection Circuitry
Built-in real-time protection against over-temperature, short circuit, over-current and under-voltage, with dedicated fault pin for status reporting.

Frequently Asked Questions
Q1: Is your currently available stock of the TAS5611APHDR component 100% genuine and original?
A: Yes, we guarantee that all TAS5611APHDR audio amplifier ICs in our stock are 100% brand-new, factory-original products from Texas Instruments. They are maintained inside climate-regulated facilities and handled strictly following standard anti-static ESD safety measures.
Q2: What is the mechanical layout benefit of the “Thermal Pad Up” design configuration on this HTQFP-64 package?
A: The exposed thermal metal pad sits on top of the chip body instead of facing the bottom PCB. This design allows you to clamp a primary heatsink directly onto the upper side of the chip, bypassing the thermal limitations of the circuit board and enabling extremely efficient heat management for massive continuous power loads.
Q3: What role does the “R” suffix play in the orderable part number TAS5611APHDR?
A: The “R” suffix directly specifies that the components are delivered in Tape and Reel format. This factory packaging is optimized for automated pick-and-place placement on large-scale SMD assembly production lines.
Q4: How can our technical division request reference schematics, output LC filter calculators, or bulk wholesale pricing structures?
A: Please complete our Quick Inquiry web form on this page with details about your processing parameters. Our application support desk will process your inquiry and dispatch the available technical documentation package within 24 hours.
