TAS5182DCA - 100W Stereo Class-D Controller | Texas Instruments
MPN: TAS5182DCA ✓ सक्रियTAS5182DCA अवलोकन
A Class-D audio power-stage controller is a semiconductor that processes a digital audio input and generates PWM drive signals for external H-bridge transistors. Unlike a conventional analog-output audio amplifier, the controller leaves power amplification to external MOSFETs, allowing output capability to scale with the selected power stage. It belongs to the digital audio amplifier and power-management IC hierarchy.
The TAS5182DCA supports stereo operation at up to 2 × 100 W RMS into a 6 Ω bridge-tied load when paired with an appropriate external power stage. Its typical total harmonic distortion plus noise is below 0.15% under the conditions identified in the manufacturer documentation. PWM input and a 0 V to 34 V supply range suit higher-power consumer and professional audio architectures.
Because TAS5182DCA is a controller rather than a self-contained power amplifier, its realized output power depends on external transistors, gate-drive implementation, supply capability, layout, thermal management, and speaker impedance. The IC controls the digital audio path while the external power devices carry the loudspeaker current. This division improves flexibility compared with integrating the output transistors into the controller package.
Typical uses include stereo loudspeaker systems, powered speakers, home-theater receivers, professional audio racks, and compact consumer audio products. The 56-HTSSOP package supports high-density PCB layouts, while the exposed thermal pad provides a thermal connection to the board copper. The 0°C to 70°C rating targets commercial ambient environments rather than extended industrial or automotive temperature ranges.
Careful power-stage layout is essential because switching currents and gate-drive timing directly affect distortion, thermal performance, and EMI. Keep high-current power loops compact, provide local supply decoupling, use low-inductance gate-drive paths, and connect the thermal pad to an appropriately sized copper area. Select the external MOSFETs and output filter against the intended load and switching requirements.
This product record combines the controller’s principal operating characteristics with application guidance, verified package information, and drop-in replacement analysis. It also distinguishes the IC’s fixed control function from the variable output power contributed by the external transistor stage, helping engineers evaluate the complete amplifier rather than relying on the nominal controller rating alone.

सामान्य अनुप्रयोग
TAS5182DCA के लिए उपयुक्त है 6 अनुप्रयोगs: Powered Stereo Speaker, Home-Theater Stereo Amplifier, Professional Audio Amplifier, Compact Speaker System, Digital Audio Power Module, Multi-Channel Audio System.
Powered Stereo Speaker
The TAS5182DCA fits a powered-speaker architecture that converts a PWM audio stream into high-power bridge-tied drive for external MOSFETs. Its controller ratings support 2 × 100 W RMS into 6 Ω loads, giving the system designer a clear target for the power stage. The external transistors determine current handling and efficiency, while the 56-pin HTSSOP controller requires a compact, carefully decoupled layout. A robust design must include speaker protection, an output filter matched to the switching stage, adequate copper for thermal conduction, and fault handling appropriate to the selected power devices.
अनुशंसित
Home-Theater Stereo Amplifier
TAS5182DCA is appropriate for a stereo home-theater power amplifier that accepts PWM audio and drives 4 Ω or 6 Ω speakers through an external power stage. The controller supports up to 100 W per channel at 6 Ω and operates with a supply range extending to 34 V, matching many high-output consumer amplifiers. Integration should account for channel matching, low-level input conditioning, output filtering, and heat removal from both the MOSFETs and the controller’s exposed pad. EMI performance depends on keeping switching current loops compact and separating sensitive audio input paths from the power stage.
अनुशंसित
Professional Audio Amplifier
The TAS5182DCA can serve as the digital power controller in a professional stereo amplifier when the external transistor stage is designed to meet the required output power and thermal limits. Its 2 × 100 W RMS capability at 6 Ω provides a useful framework for compact professional loudspeaker drives. Typical THD+N below 0.15% under specified conditions makes the device relevant to quality audio designs, but the complete amplifier must be evaluated for clipping behavior, output impedance, protection, thermal stability, and electromagnetic interference. Commercial ambient operation is specified from 0°C to 70°C.
अनुशंसित
Compact Speaker System
TAS5182DCA is suitable for compact stereo speaker systems where a controller-based architecture provides flexibility in output-device selection. Rather than fixing the loudspeaker current inside the IC, the controller allows the design engineer to choose external MOSFETs according to impedance, peak power, thermal budget, and conduction loss. This is useful when one amplifier platform must address different speaker loads. The implementation must preserve clean PWM signaling, use effective output filtering, and provide enough board copper for the controller and power devices to sustain continuous operation without excessive temperature rise.
अनुशंसित
Digital Audio Power Module
The TAS5182DCA can form the core of a modular digital audio output stage that receives PWM audio from a codec or DSP. This separation allows signal conversion, volume control, EQ, and protection to operate upstream while the controller and external transistors provide the loudspeaker drive. The 0 V to 34 V supply capability supports multiple external power-stage configurations, including the documented 100 W stereo and 200 W mono operating targets. Module designers must define the PWM interface timing and signal levels, provide local decoupling, and account for the package’s exposed thermal pad when integrating it into a higher-level board.
अनुशंसित
Multi-Channel Audio System
TAS5182DCA can be used as a stereo building block in a multi-channel amplifier system, with each section using synchronized PWM audio and its own external power stage. The controller’s 2-channel architecture simplifies balanced left/right implementation, while the 34 V maximum supply provides a broad design range for the downstream transistors. System-level considerations include channel-to-channel delay matching, independent protection, fault isolation, shared cooling, and adequate supply decoupling. The 56-pin HTSSOP footprint supports dense construction, but power-stage layout and thermal design remain the dominant constraints in high-channel-count products.

डिज़ाइन नोट्स
Separate the PWM control path from the high-current switching loops. Route gate-drive traces directly to the external MOSFETs, keep the controller supply bypass capacitors close to their pins, and provide a continuous low-impedance ground reference. The external source-current return should not share narrow paths with the controller’s sensitive signal ground. This separation reduces switching-node coupling, ground bounce, and unwanted PWM distortion.
Connect the exposed thermal pad to a continuous PCB ground-copper area using the manufacturer’s recommended via pattern. Thermal performance depends on both this controller and the external power transistors, so calculate their combined heat dissipation at maximum continuous output. Keep the power stage away from temperature-sensitive circuitry and use a copper area or heat-spreader arrangement that supports the required ambient range without exceeding device junction limits.
Do not interpret the 100 W stereo rating as a specification for the controller package alone. The external MOSFETs, gate resistance, supply impedance, output filter, PCB copper, and speaker load determine the achievable continuous power. Verify the full manufacturer reference design and worst-case thermal and electrical limits before committing to a production power stage, especially for sustained near-limit playback.
Use the shortest practical switching-current loop and consider the influence of the exposed-pad and power-ground topology on radiated emissions. Select the output-filter components using the manufacturer’s guidance for the intended switching behavior and load. Conduct pre-compliance EMC measurements with the final enclosure, cables, speaker loads, and external power-stage layout because changes at the connector or chassis can materially alter emissions.
