TAS5805MPWPR

Overview

The TAS5805MPWPR is a stereo Class-D audio amplifier from Texas Instruments, housed in a 28-pin HTSSOP package. It delivers 23 W of continuous output power into an 8-ohm load or 45 W into a 4-ohm load. The device operates on a supply voltage ranging from 4.5 V to 26.4 V and maintains a total harmonic distortion plus noise (THD+N) of 0.03%. It features digital inputs, supports multiple sampling rates up to 96 kHz, and includes integrated audio processing capabilities such as dynamic range compression and automatic gain control.

Feature Summary

• Integrates advanced audio processing including sample rate conversion, parametric equalizers, and dynamic range compression for high-fidelity sound management.
• Utilizes proprietary mixed modulation technology to achieve low static current consumption, extending battery life in portable applications.
• Features robust protection mechanisms including short-circuit protection, over-current error, and thermal warnings to ensure device reliability.

Applications

• LCD and OLED televisions
• Wireless speakers and smart home audio devices
• Soundbars and wired speaker systems

Procurement Notes

Verify the specific suffix 'PWR' indicates tape-and-reel packaging when sourcing components. Confirm RoHS compliance status and moisture sensitivity level requirements against your manufacturing process standards. Ensure the supplier provides valid traceability documentation for this Texas Instruments product code.

Selection Notes

Select this component for designs requiring high efficiency with minimal external passive components. It is suitable for applications needing flexible digital audio interfaces like I2S and TDM without master clock dependency. Consider its thermal performance and power delivery capabilities relative to the target speaker impedance and supply voltage constraints.

Part Context

This part belongs to the TAS5805M series of digital input audio amplifiers. It is designed to replace older analog input solutions by integrating signal processing directly on-chip. The MPWPR variant specifically denotes the surface-mount package configuration optimized for automated assembly processes in consumer electronics manufacturing.

Replacement Considerations

Check datasheet compatibility for pin-to-pin replacements within the same family. Verify if alternative suffixes offer identical electrical characteristics and packaging options before substitution.
