TAS5822MDCPR

Overview

The TAS5822MDCPR is a digital input, stereo, closed-loop Class-D audio amplifier with 96 kHz enhanced processing. It delivers up to 35 W per channel in 2.0 mode at 8 Ω and 24 V. The device supports multiple output configurations including bridge-tied (BTL) and parallel bridge-tied (PBTL) loads. Key electrical parameters include a THD+N of ≤ 0.06% at 1 W, an SNR ≥ 110 dB, and a power supply range of 4.5 V to 26.4 V for PVDD. It features integrated self-protection mechanisms such as over-current error, over-temperature warning/error, and under/over-voltage lock-out.

Feature Summary

• Integrated audio processor supporting sample rate conversion, dynamic EQ, and advanced DRC with automatic gain limiting.
• Flexible digital audio interface compatibility with I2S, Left Justified, Right Justified, and TDM formats without requiring MCLK.
• High-efficiency Class-D operation exceeding 90% power efficiency with reduced passive component requirements.
• Comprehensive integrated self-protection against over-current, over-temperature, and voltage anomalies.

Applications

• Soundbars
• PC audio systems
• Wireless and Bluetooth speakers
• DTV, HDTV, UHD, and multi-purpose monitors

Procurement Notes

Verify the specific ordering suffix DCPR corresponds to the TSSOP-38 package and tape-and-reel packaging configuration. Confirm that the device revision matches the required application specifications. Ensure all electrical ratings, particularly thermal resistance and operating temperature ranges, align with the target system design constraints before finalizing procurement.

Selection Notes

Select this component for applications requiring high-fidelity digital audio amplification with minimal external components. The closed-loop architecture simplifies LC filter design compared to open-loop devices. Consider the 96 kHz processing capability for advanced audio effects and the flexible power supply range for various consumer electronics designs.

Part Context

The TAS5822M belongs to Texas Instruments' family of high-performance digital input Class-D audio amplifiers.
