TAS5110DAD - 50W Stereo Class-D Power Stage | TI
N.º da peça: TAS5110DAD ✓ AtivoTAS5110DAD Visão geral
A true digital audio amplifier, or TDAA, separates digital signal processing from analog power amplification. In this architecture, a dedicated PCM-to-PWM processor converts digital audio into a differential PWM signal, while the TAS5110DAD performs the high-current power-stage function. This separation can improve efficiency, reduce analog signal-path complexity, and support digital volume and channel control when paired with a suitable modulator.
The TAS5110DAD's principal output capability is 50 W RMS per channel at 10% THD. At the more stringent 0.1% THD condition, each channel can deliver 40 W RMS. Typical total harmonic distortion plus noise is below 0.09% with a 1 kHz input signal, making the stage appropriate for high-power stereo audio systems where low clipping distortion is important. Its efficiency can exceed 90%, reducing heat generation and power-supply demand compared with inefficient linear output stages.
The device incorporates TI equibitt technology and operates within a true digital audio system rather than accepting conventional analog audio directly. A compatible TAS50xx digital audio PWM processor performs the required signal conversion. This architecture is useful when a design benefits from digital control, compact system implementation, or elimination of a conventional analog input and voltage-gain amplifier stage. The external power architecture and load capability still require careful layout and thermal planning.
Typical applications include powered stereo speakers, home-theater and multimedia amplifiers, compact consumer audio systems, digital active speakers, and industrial audio equipment operating from suitably rated power supplies. The 50 W per-channel output target is suitable for demanding speaker loads, while the high-efficiency Class-D output stage helps reduce board-space requirements compared with a linear amplifier of similar output power.
The main design consideration is the power path. Use a low-impedance power supply and ground layout, keep high-current switching loops compact, and provide robust filtering between the switching output and sensitive audio circuitry. Thermal performance depends on the exposed package thermal pad, copper area, airflow, enclosure temperature, and sustained output level, so thermal performance must be verified in the finished enclosure rather than estimated from the package name alone.
This product page organizes the TAS5110DAD specifications, verified source links, application guidance, design notes, and replacement considerations into one engineering reference. The technical emphasis is on output power, distortion, efficiency, digital-system integration, thermal implementation, and the practical differences between documented device variants.

Aplicações típicas
TAS5110DAD é adequado para 6 aplicaçãos: Powered Stereo Speakers, Home-Theater Stereo Amplification, Digital Active Speaker Systems, Multimedia Audio Amplifiers, Industrial Audio Equipment, High-Efficiency Audio Power Modules.
Powered Stereo Speakers
The TAS5110DAD fits powered stereo speakers requiring up to 40 W RMS per channel at 0.1% THD or 50 W RMS per channel at 10% THD. It accepts differential PWM audio from a compatible TAS50xx processor and drives a Class-D output stage that can exceed 90% efficiency. This reduces amplifier heat and power-supply demand compared with a conventional linear stage, while the 32-pin HTSSOP package requires careful thermal-pad and copper-area implementation.
Recomendado
Home-Theater Stereo Amplification
The TAS5110DAD can provide high-power stereo channels for powered home-theater speakers and compact multimedia amplifiers. Its 50 W RMS per channel capability at 10% THD gives sufficient headroom for music playback, while 40 W RMS at 0.1% THD supports lower-distortion operation. A TAS50xx processor supplies the 3.3 V differential PWM stream, and the finished amplifier must be evaluated for sustained two-channel thermal load, speaker impedance, and enclosure temperature.
Recomendado
Digital Active Speaker Systems
The TAS5110DAD is appropriate for digital active speakers where a host processor performs decoding, volume control, or channel routing before sending PWM audio to the power stage. Separating digital processing from the high-current output function reduces the need for a conventional analog voltage-gain amplifier and supports compact power-amplifier modules. System design must synchronize the processor and power-stage control sequence and verify the 3.3 V PWM interface across all operating states.
Recomendado
Multimedia Audio Amplifiers
The TAS5110DAD can serve as the stereo output stage in multimedia amplifier modules for desktop audio, display accessories, and compact entertainment systems. Its Class-D architecture can exceed 90% efficiency according to the manufacturer datasheet, helping maintain manageable heat in space-constrained enclosures. Use a compatible digital modulator, provide local high-current supply decoupling, and confirm that speaker loading remains within the device's thermal and electrical operating limits.
Recomendado
Industrial Audio Equipment
The TAS5110DAD supports industrial audio modules that need efficient stereo power amplification and controlled digital signal processing. A TAS50xx processor can generate the differential 3.3 V PWM drive required by the power stage, allowing the system to retain digital control over volume and processing. The amplifier's 40 W RMS per channel rating at 0.1% THD is useful for high-output industrial speakers, but the enclosure should account for sustained thermal dissipation and conducted switching noise.
Recomendado
High-Efficiency Audio Power Modules
The TAS5110DAD is suited to modular audio products that prioritize power density and amplifier efficiency. Its Class-D output stage can exceed 90% efficiency, and its 40 W to 50 W RMS per-channel ratings provide useful output for demanding loads without relying on a large linear output transistor arrangement. The 32-pin HTSSOP construction supports compact surface-mount assembly, although adequate exposed-pad copper, heat spreading, and power-supply capacity remain essential at sustained high output.

Notas de projeto
Estimate worst-case dissipation from the actual output power, supply voltage, efficiency, and number of active channels rather than using only the headline RMS rating. Estimated: at 50 W output power and 90% efficiency, each conducting channel dissipates approximately 5.6 W before adding control-circuit and idle losses. Verify the resulting junction temperature using the manufacturer thermal information, exposed-pad copper, PCB area, airflow, and enclosure temperature.
Separate the high-current Class-D output and power-supply paths from sensitive digital-audio circuitry. Keep switching-current loops compact, provide local bulk and high-frequency decoupling at the device, and use the manufacturer land pattern for the HTSSOP exposed thermal pad. The power and ground pins should connect to planes that can carry both channels without excessive voltage drop or added switching noise.
Do not treat TAS5110DAD as a conventional analog-input amplifier. It requires differential PWM signals generated by a compatible digital audio processor, and the system must handle startup, shutdown, and mute sequencing correctly. Also confirm that the selected speaker impedance and power-supply limits support the intended 40 W to 50 W per-channel operating point before beginning PCB layout.
Plan output filtering and return-current paths during schematic definition. The Class-D switching node can produce high-frequency electromagnetic energy that may couple into analog, microphone, radio, or network circuitry through shared power and ground systems. Use the recommended filter components and layout topology, keep sensitive interconnects away from output switching nodes, and verify emissions and audio idle noise in the completed assembly.
