TAS2555YZR - 5.7W Class-H Smart Amp | Texas Instruments
MPN: TAS2555YZR ✓ সক্রিয়TAS2555YZR সারাংশ
A Class-D smart amplifier is an audio power amplifier that converts digital or analog audio signals into a high-efficiency switching output suitable for driving a speaker. It belongs to the broader hierarchy of audio amplifier IC, amplifier IC, signal-processing semiconductor, and power-management electronics. Unlike a simple analog power stage, the TAS2555 integrates digital control, programmable audio functions, speaker sensing, and protection into a system-on-chip-style audio solution.
The TAS2555YZR’s headline features include 5.7 W output power, digital input, integrated speaker protection, advanced equalization, and an 8.5 V Class-H boost. The boost function supports higher speaker voltage than the basic Class-D output stage, while integrated protection is intended to improve reliability in connected speaker systems. These functions target compact consumer and connected-audio equipment where board area, thermal performance, and speaker fault handling are important design constraints.
Technically, the device combines a digital audio interface with a mono Class-D output stage and Class-H boost capability. Its architecture allows audio processing and speaker management to be integrated around the amplifier rather than implemented entirely as separate discrete functions. The verified manufacturer material describes the TAS2555 as a state-of-the-art Class-D audio amplifier and full system-on-chip solution, although detailed interface rates, distortion limits, thermal resistance, and detailed electrical limits require the manufacturer datasheet.
Typical applications include Bluetooth and wireless speakers, smart speakers, portable audio products, sound bars, compact consumer-audio systems, and other embedded mono-speaker platforms. A designer can use the digital input to reduce analog signal-path noise, enable programmable equalization, and centralize speaker protection. The package’s 42-ball BGA construction supports compact layouts but requires careful PCB escape routing and assembly-process planning.
When designing around the TAS2555YZR, verify the complete 42-pin YZ ball map, exposed-pad requirements, boost inductor requirements, speaker configuration, and recommended decoupling in the Texas Instruments datasheet. PCB layout should prioritize clean power and ground distribution, short switching-current loops, controlled high-current boost routing, and uninterrupted digital and speaker-sensing connections.
This product page consolidates verified manufacturer and distributor information into an engineering-focused comparison of features, package constraints, sourcing details, and practical design considerations. It also distinguishes verified facts from parameters that still require datasheet confirmation, helping teams evaluate the TAS2555YZR without inventing missing electrical data.

সাধারণ ব্যবহার
TAS2555YZR এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Bluetooth Speaker Output Stage, Smart Speaker Voice Terminal, Portable Audio Device, Soundbar Speaker Channel, Industrial Audio Terminal, Connected Audio Module.
Bluetooth Speaker Output Stage
The TAS2555YZR fits a compact Bluetooth speaker because it combines a 5.7 W mono Class-D output with a digital input and an 8.5 V Class-H boost. A wireless-audio SoC can deliver digital samples directly to the smart amplifier, reducing the need for a separate analog audio path. The integrated speaker protection and advanced EQ support a more complete output subsystem in a small board area. Designers should still confirm the supported digital format, sample rate, and host-control interface against the datasheet, then route the 42-DSBGA power, ground, digital, boost, and speaker-sensing connections according to the manufacturer layout.

Smart Speaker Voice Terminal
The TAS2555YZR is suitable for the voice-speaker terminal of a smart speaker or voice assistant because it provides 5.7 W of mono Class-D output in a compact 42-DSBGA package. The digital input allows the system’s audio processor to remain the central source for decoding and mixing, while the amplifier handles power conversion and speaker drive. Its 8.5 V Class-H boost, advanced EQ, and integrated speaker protection can support consistent output behavior across compatible speaker loads. Integration requires careful BGA escape routing and verified boost-component selection, with the complete electrical and acoustic limits taken from the Texas Instruments datasheet.

Portable Audio Device
The TAS2555YZR can serve as the loudspeaker amplifier in a portable audio product where low board area, digital audio control, and integrated protection are important. Its 5.7 W mono rating is appropriate for compact single-speaker systems, while the digital input can simplify the connection to a mixed-signal audio processor. The 8.5 V Class-H boost offers additional voltage capability for compatible speaker configurations, and advanced EQ allows system-level response shaping. Battery-powered implementations must still evaluate supply limits, amplifier efficiency, thermal behavior, and the speaker impedance range using the manufacturer documentation before committing the design.

Soundbar Speaker Channel
The TAS2555YZR is applicable to a soundbar channel designed around a compact digital audio architecture because it delivers 5.7 W of mono Class-D output with integrated speaker protection. If a soundbar uses one amplifier per driver or a particular driver in a separate enclosure, the TAS2555 can provide a dedicated amplification channel. Digital input, advanced EQ, and the 8.5 V Class-H boost help integrate audio shaping and drive capability within the main processor domain. The 42-DSBGA package supports compact routing, but production designs require exact ball mapping, acoustics validation, thermal assessment, and confirmation that the speaker load falls within the manufacturer’s supported operating conditions.
সুপারিশকৃত
Industrial Audio Terminal
The TAS2555YZR can be considered for an industrial audio terminal that uses digital audio and requires a protected mono speaker output. Its integrated speaker protection is valuable where cables, connectors, or speakers may be exposed to abnormal conditions, while the -40 °C to +85 °C operating-temperature range supports a wider range of equipment environments than a consumer-only part. The 5.7 W output and 8.5 V Class-H boost suit compact announcement or notification speakers. Final qualification requires verification of the electrical limits, protection behavior, reliability requirements, and system thermal design because those details were not included in the supplied verified snippets.

Connected Audio Module
The TAS2555YZR is well matched to a connected-audio module that separates digital processing from loudspeaker amplification. The host processor can provide digital audio, apply programmable equalization, and control the smart amplifier while the TAS2555 handles the 5.7 W mono output stage and 8.5 V boost. Integrated protection reduces the external circuitry required for a more robust speaker connection. This partitioning can simplify a compact module containing wireless connectivity, a codec or processor, and a speaker driver. Engineers must validate digital timing, clock requirements, control-register compatibility, and the 42-ball PCB footprint against the manufacturer datasheet before layout release.

ডিজাইন নোট
Use the Texas Instruments TAS2555 reference layout as the controlling document for the 42-pin DSBGA (YZ). The supplied web data does not include the ball map or escape-routing pattern, so engineers must not infer connections from package position alone. Place input, output, boost, power, and ground components according to the manufacturer layout, and preserve short return paths for switching currents to reduce radiated emissions and voltage disturbance.
Validate the boost inductor, supply limits, output configuration, and speaker impedance against the current Texas Instruments datasheet before layout release. The verified information confirms a 5.7 W mono Class-D output with an 8.5 V Class-H boost, but it does not provide the input-voltage range or detailed dissipation limits. Those missing values directly affect battery sizing, thermal design, component selection, and the protection strategy.
Do not treat another 5.7 W Class-D amplifier as a drop-in replacement merely because its power rating and package family appear similar. The TAS2555YZR integrates a digital input, Class-H boost, speaker sensing, advanced EQ, and speaker protection. A valid substitute must match the 42-DSBGA footprint, ball functions, digital timing, control interface, boost behavior, and electrical limits; otherwise the PCB and firmware may both require changes.
