TAS5805MPWP

Overview

The Texas Instruments TAS5805MPWP is a stereo, closed-loop Class-D audio amplifier featuring digital inputs and enhanced processing capabilities. It delivers 23 W of output power into an 8-ohm load at 21 V with 1% THD+N, or 45 W in mono mode into a 4-ohm load. The device operates on a supply voltage range of 4.5 V to 26.4 V for PVDD, with DVDD and I/O supporting 1.8 V or 3.3 V. It achieves a signal-to-noise ratio of at least 107 dB (A-weighted) and total harmonic distortion plus noise of 0.03%. The component is housed in a 28-pin HTSSOP package and supports sampling rates up to 96 kHz.

Feature Summary

• Integrates advanced audio processing features including sample rate conversion, parametric equalizers, dynamic range compression, and automatic gain control within a 96-kHz architecture.
• Utilizes a proprietary hybrid modulation scheme that enables inductor-less operation for most supply voltages up to 14 V, reducing passive component count and board space.
• Provides flexible digital audio interface options including I2S, Left-Justified, Right-Justified, TDM, and 3-wire formats without requiring a master clock.
• Includes comprehensive protection mechanisms such as short-circuit protection, over-current error, thermal warnings, and under-voltage/over-voltage lockout.

Applications

• LCD and OLED televisions
• Wireless speakers and smart speakers with voice assistants
• Soundbars and wired speaker systems
• Bookshelf stereo systems and desktop computers

Procurement Notes

Verify the specific suffix 'WP' against the manufacturer's current datasheet to confirm the tube packaging configuration, as the 'WPR' variant indicates tape-and-reel packaging. Ensure compatibility with the required operating temperature range of -25°C to +85°C for your application environment. Confirm RoHS compliance status and moisture sensitivity level requirements before finalizing procurement specifications.

Selection Notes

Select this component when a digital input interface is preferred over analog inputs to simplify system design and reduce external processing requirements. Choose the TAS5805MPWP for applications requiring high efficiency and low idle power consumption to extend battery life in portable devices. Consider this part for designs needing integrated audio enhancement features without external DSPs, particularly where board space constraints limit the use of large inductors.

Part Context

The TAS5805MPWP belongs to the TAS5805M family of digital input, closed-loop Class-D amplifiers from Texas Instruments. This series is designed to provide high-fidelity audio performance with minimal external components. The device integrates a complete audio processor, allowing for direct connection to digital audio sources while maintaining low power dissipation and high efficiency across various supply voltages.

Replacement Considerations

The TAS5805MPWPR is a pin-compatible alternative with identical electrical characteristics but differs in packaging format, utilizing tape-and-reel instead of tubes. Other family members like the TAS5806M offer similar functionality but may have variations in specific processing features or power ratings; verify datasheet details for exact substitution suitability.
