TAS5825MRHBR

Overview

The TAS5825MRHBR is a stereo, inductor-less, digital-input, closed-loop Class-D audio amplifier with integrated audio processing. It supports supply voltages from 4.5 V to 26.4 V and delivers up to 38 W per channel in stereo mode at 8 Ω loads. The device features a powerful DSP core supporting flexible sampling rates including 96 kHz and 192 kHz. It integrates an asynchronous sample rate converter (SRC) for seamless input handling. Key electrical parameters include THD+N ≤0.03% at 1 W, SNR ≥110 dB, and power efficiency exceeding 90%. The component operates within a temperature range of -25°C to +85°C.

Feature Summary

• Integrated high-performance DSP kernel enabling advanced audio processing such as dynamic EQ, bass enhancement, and intelligent thermal protection algorithms.
• Asynchronous sample rate converter automatically detects and adapts to varying input sampling rates to prevent audio artifacts.
• Closed-loop architecture provides superior audio fidelity while eliminating the need for large external inductors or electrolytic capacitors.
• Flexible digital audio interface support including I2S, LJ, RJ, TDM, and SDOUT without requiring a master clock.

Applications

• Digital televisions, HDTVs, UHD displays, and multifunction monitors
• Soundbars, subwoofers, and laptop/PC speaker systems
• Wireless and Bluetooth-enabled speakers
• Smart speakers equipped with voice assistants

Procurement Notes

Verify the specific suffix 'RHBT' against official Texas Instruments documentation to confirm package type and temperature grade accuracy. Ensure compatibility with I2C configuration requirements during integration. Confirm that the selected variant matches the required operating voltage range and thermal specifications for the target application environment before finalizing procurement.

Selection Notes

Select this component when designing compact audio solutions requiring high power output without bulky passive components. The integrated DSP allows for customized audio tuning without external processors. Consider the 32-VQFN package for space-constrained PCB layouts. Ensure the system design accommodates the digital input interfaces and I2C control lines necessary for proper initialization and operation.

Part Context

This device belongs to the TAS5825M family of digital input Class-D amplifiers. It shares architectural similarities with other TI audio products like the TAS5805M but offers higher power density and extended processing capabilities. The family is designed to replace traditional analog amplifier designs by integrating DAC and amplifier functions into a single monolithic solution.
