TAS5827RHBR

Overview

The TAS5827RHBR is a stereo high-performance, closed-loop Class-D amplifier with an integrated audio processor supporting up to 192kHz sample rates. It operates on a PVDD supply ranging from 4.5V to 26.4V and a DVDD supply of 1.8V or 3.3V. The device delivers up to 57W per channel in BTL mode at 6Ω loads with 25V supply, or 112W in PBTL mode at 3Ω. It features >90% power efficiency, THD+N ≤ 0.03%, and SNR ≥ 110dB. The component is housed in a 32-pin VQFN (RHB) package measuring 5mm × 5mm.

Feature Summary

• Integrates proprietary audio envelope tracking Class-H control algorithm for increased system efficiency
• Supports flexible digital audio I/O including I2S, LJ, RJ, and TDM formats without requiring MCLK
• Includes comprehensive internal DSP processing such as 12 Biquad filters, DRC, and AGL
• Provides robust self-protection mechanisms including over-current, over-temperature, and UVLO

Applications

• Battery-powered speakers
• Wireless Bluetooth speakers
• Soundbars and subwoofers
• Smart speakers

Procurement Notes

Verify the specific ordering suffix RHBR corresponds to the VQFN-32 package configuration required for your design. Confirm that the intended application voltage range falls within the specified 4.5V to 26.4V limits for PVDD. Ensure thermal management strategies align with the junction-to-ambient thermal resistance specifications provided in the datasheet.

Selection Notes

Select this component when high-efficiency audio amplification with integrated digital signal processing is required. It is suitable for designs needing software-configurable parameters via I2C or hardware-controlled operation. Consider its Class-H capabilities for optimizing battery life in portable applications while maintaining high output power levels.

Part Context

This part belongs to the Texas Instruments TAS5827 family of digital input, high-efficiency closed-loop Class-D amplifiers. It is designed to replace open-loop solutions by reducing passive component count and offering superior audio performance through closed-loop feedback and advanced DSP integration.
