TAS5152DKD - 125W Stereo Class D Power Stage | Texas Instruments
MPN: TAS5152DKD ✓ فعالTAS5152DKD نمای کلی
A Class D power stage is a switching amplifier category that uses pulse-width-modulated drive signals to transfer energy to a loudspeaker. Compared with a conventional linear audio amplifier, the Class D architecture can achieve higher conversion efficiency while reducing the amount of heat that must be removed during operation. The TAS5152DKD belongs to the broader hierarchy of audio amplifiers, power amplifiers, power-management semiconductors, and integrated circuits.
The integrated design includes gate drivers, four matched and electrically isolated enhancement-mode N-channel power DMOS transistors, and protection and fault-reporting circuitry. Its 125 W stereo output capability suits powered speakers, home-theater amplification, professional audio, and other high-output audio designs. Operation from a 10.8 V to 13.2 V supply supports conventional 12 V power-system architectures, while the listed 0 V to 37 V operating-voltage range provides additional design context.
The TAS5152 is described by Texas Instruments as a third-generation, high-performance integrated stereo digital amplifier power stage with an improved protection system. Combining the output transistors and their drivers within the power-stage package reduces the number of discrete power devices required around the amplifier. The four electrically isolated DMOS devices support the full-bridge structure used by each Class D output channel.
Typical applications include 125 W stereo speaker amplification, powered loudspeakers, home-theater receiver output stages, multichannel audio systems, and compact consumer or professional audio products. System designers should select the power supply, output filter, speaker load, PCB copper, and thermal solution together because output power alone does not establish safe operating conditions.
For PCB implementation, follow the manufacturer pin-description table, exposed-pad connection guidance, recommended output-filter layout, and thermal design recommendations. A 12 V-class supply is the intended operating environment, and the design must preserve adequate headroom, signal integrity, output filtering, and heat-spreading paths to sustain the advertised 125 W result.
This page combines the verified device specifications, application guidance, package information, and a parameter-level engineering comparison that helps engineers evaluate the TAS5152DKD for high-power stereo amplifier designs.

کاربردهای معمول
TAS5152DKD مناسب است برای 6 کاربردs: Powered Stereo Loudspeakers, Home-Theater Amplifier, Multichannel Audio Systems, Professional Audio Amplification, Consumer Audio Systems, Digital Audio Signal-Chain Power Stage.
Powered Stereo Loudspeakers
The TAS5152DKD fits a powered-speaker output stage requiring 125 W per channel into a 4-ohm loudspeaker at 10% THD+N. Its integrated gate drivers and four matched, electrically isolated enhancement-mode N-channel DMOS transistors provide the high-power switching output stage in one 36-pin HSSOP package. The 10.8 V to 13.2 V supply range suits a nominal 12 V amplifier architecture. In a finished loudspeaker, the designer must implement the manufacturer-recommended output filters, speaker connections, fault handling, and PCB copper paths while accounting for continuous-load thermal dissipation.

Home-Theater Amplifier
TAS5152DKD can provide the high-power stereo section of a home-theater amplifier while preserving a compact output-stage implementation. Each channel supports up to 125 W into 4 ohms at 10% THD+N, making the device relevant to powered speakers, sound-bar amplification, and compact home-theater receivers. The device accepts a 10.8 V to 13.2 V supply, but channel count, thermal requirements, protection behavior, and system-level output filtering determine whether multiple power stages are needed. A practical implementation should follow the manufacturer layout and thermal guidance rather than treating the 125 W rating as independent of board design.

Multichannel Audio Systems
The TAS5152DKD is useful when a multichannel audio system needs scalable stereo power stages for high-impedance or compact powered-speaker loads. Its two-channel architecture supports left and right amplification, while multiple matched devices can serve additional listening zones or surround channels where the power supply and thermal system allow. The 125 W per-channel specification applies to a 4-ohm load at 10% THD+N, so channel count and simultaneous loading must be evaluated carefully. Designers should use the pin-description table, output-filter layout, and fault-reporting strategy from the manufacturer documentation when allocating and routing multiple devices.

Professional Audio Amplification
TAS5152DKD can serve as the stereo output stage in compact professional audio equipment where high output power and integrated switching transistors are priorities. The 125 W per-channel capability into 4 ohms at 10% THD+N provides substantial headroom for stage monitors, active speakers, and auxiliary amplification systems. Its 10.8 V to 13.2 V operating supply supports a 12 V-class power architecture, while integrated protection and fault reporting assist system-level fault management. Production designs still require verified output filters, correct speaker impedance behavior, stable rail layout, and a thermal solution matched to the enclosure and continuous duty cycle.
پیشنهادی
Consumer Audio Systems
TAS5152DKD suits consumer audio products that need higher output power than a small integrated amplifier can provide while retaining a single-package power-stage solution. A compact stereo amplifier, sound bar, active bookshelf speaker, or media system can use the 36-pin HSSOP device for two 125 W channels into 4-ohm loads at the stated distortion criterion. The 10.8 V to 13.2 V supply range integrates naturally with a nominal 12 V power rail. Designers should account for the heat generated at sustained high output, protect the loudspeaker outputs with the recommended network, and place input, power, and thermal connections according to the manufacturer layout guidance.
پیشنهادی
Digital Audio Signal-Chain Power Stage
TAS5152DKD is appropriate for a digital audio signal chain that separates conversion from high-current loudspeaker drive. A stereo DAC such as the PCM1725DR can generate the left and right analog signals, while the TAS5152DKD supplies the 125 W per-channel Class D output stage into 4-ohm speakers. This separation lets the output power amplifier remain optimized for switching efficiency and thermal performance rather than signal conversion. Interface and filtering decisions must prevent converter artifacts or high-frequency switching energy from reaching the drivers, and the system should include appropriate speaker protection and fault monitoring around the power stage.

یادداشت‌های طراحی
Estimated: at 125 W of useful output power per channel and an assumed amplifier efficiency of 80%, each channel dissipates approximately 31.25 W. Using 125 W total for two channels gives an estimated 62.5 W heat load, but the actual loss depends on efficiency, THD+N, rail voltage, load, and modulation. Size the PCB copper and enclosure heat path using the manufacturer thermal guidance and verify the maximum junction temperature on the assembled system.
Place input, power, ground, and output-filter connections according to the manufacturer PCB layout, keeping high-current output paths compact and separated from sensitive audio inputs. The exposed thermal pad and package ground connections require the prescribed copper pattern, and thermal vias should be placed where they improve heat flow without compromising the recommended layout. Do not infer the exposed-pad connection solely from the package outline.
Do not treat 125 W as a guaranteed continuous output from the package alone. The rating is 125 W per channel into 4 ohms at 10% THD+N, and the achievable result also depends on the 10.8 V to 13.2 V supply range, output-filter implementation, PCB thermal resistance, enclosure temperature, and load behavior. Confirm the operating mode and all thermal limits in the manufacturer datasheet before committing the design.
