TAS5715PHP - 25W Stereo Class-D Audio Amplifier | Texas Instruments
MPN: TAS5715PHP ✓ সক্রিয়TAS5715PHP সারাংশ
A Class-D audio power amplifier is an efficient switching power stage that drives stereo bridge-tied speakers using digital input data. Within the broader semiconductor hierarchy, the TAS5715PHP is a digital-input audio power amplifier, a member of the Class-D amplifier family, and an audio amplifier IC used in professional and consumer audio power-management systems. Its 48-pin surface-mount HTQFP package supports dense integration on audio amplifier boards.
The verified product information specifies 25 W output into an 8 ohm load from an 18 V supply, together with support for 50 W operation in parallel bridge-tie load, or PBTL, mode with a 4 ohm load. The device accepts digital audio data for up to two discrete channels, allowing a digital audio processor or MPEG decoder to feed the stereo output stages without separate analog-to-digital conversion.
The TAS5715 combines speaker signal processing with power amplification. Integrated features include equalization, dynamic range control, high-pass filtering, and DC protection. Headphone PWM outputs add a second use case beyond loudspeaker drive, while efficient Class-D operation reduces the heat normally associated with linear audio output stages. The open-loop architecture provides digital control of the audio signal path rather than relying only on conventional analog feedback.
Typical applications include powered stereo speakers, compact consumer audio systems, multimedia equipment, sound bars, and digital-audio source products. Its serial digital input works naturally with digital audio processors and MPEG decoders, while the 25 W stereo rating targets conventional 8 ohm speaker loads. The 50 W PBTL capability provides additional flexibility for suitable 4 ohm loads when the amplifier, thermal design, and board layout support that operating mode.
Power-supply and thermal layout are critical because Class-D output current and switching losses produce heat in the HTQFP package. The exposed-pad area and surrounding PCB copper must be designed for effective heat transfer, and speaker outputs must not be connected to ground or chassis. Input routing, power ground separation, and output-filter selection also require careful layout to preserve audio performance and suppress unwanted switching artifacts.

সাধারণ ব্যবহার
TAS5715PHP এর জন্য উপযুক্ত 6 অ্যাপ্লিকেশনs: Powered Stereo Speakers, Sound Bars and Compact Audio Systems, Multimedia Equipment, Digital Audio Source Products, Headphone-Enabled Portable Audio, Digital Audio Evaluation and Development.
Powered Stereo Speakers
The TAS5715PHP fits powered stereo speakers because it delivers 25 W per channel into an 8 ohm load from an 18 V supply and accepts digital audio data for two channels. It can sit between a digital audio processor or MPEG decoder and bridge-tied speaker outputs, eliminating separate analog power amplifiers. Integrated EQ, dynamic range control, high-pass filtering, and DC protection reduce external signal-chain requirements. The 48-pin HTQFP package requires careful exposed-pad thermal layout, while the 8 V to 26 V PVDD range accommodates common internal power systems.

Sound Bars and Compact Audio Systems
A sound bar or compact audio system benefits from the TAS5715PHP's 25 W stereo output and integrated digital signal processing. One serial data input can carry up to two discrete audio channels from a compatible processor, while EQ and dynamic range control help adapt output to different listening environments. The device can provide 50 W in PBTL mode with a 4 ohm load when the system qualifies for that operating condition. Board designers should preserve ground separation between sensitive input and power-return paths and provide substantial thermal copper around the 7 mm by 7 mm HTQFP package.

Multimedia Equipment
The TAS5715PHP is suitable for multimedia equipment requiring efficient stereo speaker drive from a digital source. Its documented 25 W per-channel capability into 8 ohms supports conventional powered-speaker arrangements, and the digital serial input integrates directly with processors or MPEG decoders. Integrated high-pass filtering, EQ, dynamic range control, and DC protection can simplify the audio signal path. In compact equipment, designers must account for heat from Class-D output stages by allocating adequate exposed-pad copper and controlling the PVDD supply layout to minimize switching noise.

Digital Audio Source Products
The TAS5715PHP works well in digital audio source products because its serial interface accepts up to two discrete channels and its output stage provides 25 W per channel into 8 ohms. This allows a digital decoder to feed a Class-D speaker stage directly rather than requiring a separate analog power amplifier. Equalization, dynamic range control, high-pass filtering, and DC protection are integrated into the device. The design must still verify the manufacturer's digital control requirements, provide a stable 8 V to 26 V PVDD rail, and implement output filtering and thermal management according to the official datasheet.

Headphone-Enabled Portable Audio
The TAS5715PHP supports portable-audio designs that need both headphone playback and loudspeaker output. Its integrated headphone PWM outputs complement the 25 W stereo Class-D speaker stage, allowing a single digital-input device to serve multiple listening paths. Digital EQ and dynamic range control can help manage content-dependent level differences, while the 8 V to 26 V supply range provides design flexibility. Because this is a 48-pin HTQFP device, portable products also need a compact but thermally capable board layout, careful antenna and switching-node separation, and verified input-level compatibility.
সুপারিশকৃত
Digital Audio Evaluation and Development
The TAS5715PHP is useful in audio development platforms because Texas Instruments provides the TAS5715EVM to demonstrate the capabilities of the device. Engineers can evaluate the 25 W stereo Class-D output, digital input behavior, integrated EQ, dynamic range control, high-pass filtering, DC protection, and headphone PWM outputs before integrating the 48-pin HTQFP into production hardware. The evaluation module can shorten initial bring-up work, but any new design still requires independent PVDD decoupling, speaker-output filtering, thermal analysis, and signal-integrity review based on the manufacturer application guidance.

ডিজাইন নোট
Design the exposed-pad thermal path before committing the PCB stack-up and enclosure. At the documented 25 W per-channel condition, actual heat generation depends on PVDD, output waveform, speaker impedance, and duty cycle. Use the maximum copper area permitted by the manufacturer layout, connect the exposed pad to the appropriate ground plane through the prescribed thermal-via pattern, and verify junction temperature in the final enclosure under worst-case continuous playback.
Place the PVDD decoupling capacitors directly beside the power pins and keep the Class-D switching loop as small as practical. Keep the digital serial interface and control traces away from speaker outputs and power-converter nodes, and provide an uninterrupted return path for the exposed pad. Because the supplied evidence does not include the recommended capacitor values or complete land pattern, use the official Texas Instruments datasheet and evaluation-module layout rather than relying on generic values.
Treat the digital audio input, clock, and control signals as potentially vulnerable to Class-D switching noise. Route them over a continuous ground reference, avoid crossings with high-current speaker outputs, and observe the datasheet's clock and data timing requirements. Confirm the source codec's voltage levels and timing compatibility before layout release. The speaker outputs must remain isolated from ground and chassis to avoid damaging the bridge-tied output stage.
Do not treat the 50 W PBTL rating as permission to use any 4 ohm speaker without checking thermal and electrical limits. The verified synopsis specifically states 50 W support in PBTL mode with a 4 ohm load, but operation also depends on supply voltage, board thermal capability, signal level, and manufacturer recommendations. Likewise, confirm pin functions from the official datasheet because the supplied data identifies the 48-pin HTQFP package but does not provide the complete numbered pin map.
