TAS5717PHP - 10W Stereo Class-D Amplifier | Texas Instruments
MPN: TAS5717PHP ✓ فعالTAS5717PHP جائزہ
A Class-D audio amplifier is a switching power amplifier that uses transistor output stages to deliver high audio power efficiently. In bridge-tied-load operation, each output contributes to the voltage across the speaker. This architecture belongs to the broader power-amplifier and audio-IC hierarchy, where efficiency, thermal performance, output-filter requirements, and signal-path integration are central design considerations.
Principal device features include 2 x 10 W stereo output capability, digital audio input, a 4.5 V to 26 V operating supply range, and integrated capacitor-free headphone outputs. The verified specifications also report THD+N of 0.13% at 1 W into an 8-ohm load with PVDD at 8 V. A single serial-data input supports programmable routing of two discrete audio channels, making the device suitable for systems receiving audio from digital processors, MPEG decoders, and other digital audio sources.
The amplifier's integrated digital signal path reduces the need for a separate analog input interface, while its headphone stage offers a practical transition between loudspeaker and headphone outputs in compact consumer equipment. The PHP package provides 48 pins and a 7 x 7 mm body. Because no verified mechanical drawing, pin table, exposed-pad recommendation, or complete power-dissipation table was included in the supplied data, those implementation details must be confirmed in the manufacturer datasheet before layout is released.
Typical uses include powered speakers, multimedia speaker systems, compact consumer audio products, and equipment requiring digital audio input plus both stereo loudspeaker and headphone outputs. Because the loudspeaker interface is a bridge-tied load, neither output should be referenced to system ground without an appropriate coupling or isolation arrangement. The integrated headphone output may reduce the external component count relative to designs using a separate headphone amplifier.
A key design consideration is power-rail planning: the verified 4.5 V to 26 V range must cover startup, load-transient, and supply-noise requirements without exceeding the device limits. PCB designers should follow the manufacturer's land pattern, exposed-pad, thermal, output-filter, and decoupling guidance exactly. Speaker and headphone outputs also require EMI and EMI-risk review because Class-D switching currents can couple into sensitive analog or radio-frequency circuitry.
This page consolidates the verified manufacturer and distributor information with structured specifications, purchase-intent guidance, application analysis, and honest replacement criteria. It also distinguishes confirmed TAS5717PHP characteristics from parameters that still require datasheet-level verification, helping engineers avoid treating generic Class-D amplifier data as device-specific evidence.

Compact Powered Stereo Speaker
The TAS5717PHP fits a compact powered speaker because it delivers 2 x 10 W stereo output from a digital audio source and operates from 4.5 V to 26 V. The device can sit between a digital audio processor and a pair of bridge-tied-load speakers, avoiding a separate analog-input stage. Its 48-pin HTQFP (PHP) package has a 7 x 7 mm body, which supports compact layouts when the manufacturer's thermal and exposed-pad guidance is followed. Continuous output still depends on supply voltage, 8-ohm loading, copper area, and thermal conditions; the verified data does not provide thermal resistance, so those limits must be checked before committing to sustained high-power operation.

Multimedia Speaker System
The TAS5717PHP is appropriate for a multimedia speaker system requiring efficient stereo drive and flexible digital sourcing. One serial data input supports two discrete audio channels, allowing a digital processor or MPEG decoder to feed the amplifier directly. Its reported THD+N of 0.13% at 1 W into 8 ohm with PVDD at 8 V provides a useful low-power fidelity reference when selecting an amplifier. The integrated capacitor-free headphone output can simplify a dual-output product intended to serve both speakers and headphones, although the exact headphone load range and output power require confirmation in the manufacturer datasheet.

Digital Audio Dock
A digital audio dock can use the TAS5717PHP to accept processed digital audio and drive a stereo speaker pair while also serving headphones. The single serial-data interface reduces the need for a separate DAC-to-analog input path when the upstream processor already supplies compatible digital audio. Its 4.5 V minimum operating supply can support integrated portable and desktop designs, while the 26 V maximum provides headroom for higher-voltage implementations. Integration must be planned around verified rail sequencing, clock requirements, supported data formats, and the fact that the bridged speaker outputs cannot be connected directly to chassis ground.

Headphone and Speaker Hybrid
The TAS5717PHP is particularly relevant to hybrid products that must drive both headphones and stereo speakers. Its integrated DirectPath ground-centered headphone output removes the need for a conventional output coupling capacitor in that signal path, while the Class-D stage provides 2 x 10 W speaker capability. This combination can reduce board area and component count relative to using a separate headphone amplifier. The supplied excerpts do not quantify headphone output power, impedance, distortion, or channel crosstalk, so the current TI datasheet must be checked before defining the usable headphone load or analog output behavior.

Consumer Audio Appliance
The TAS5717PHP can support a consumer audio appliance that receives digital audio and needs efficient, compact stereo amplification. The 2 x 10 W capability is suitable for compact speaker systems, while the 7 x 7 mm HTQFP package helps constrain board area. Its verified operating range of 0 C to 85 C suits many indoor consumer products, but enclosure temperature, speaker sensitivity, and sustained output must be included in the thermal assessment. The design should follow the official land pattern and use the verified 4.5 V to 26 V operating range without exceeding component or output-current limits that must be taken from the datasheet.

Digital Soundbar Speaker Module
The TAS5717PHP is suitable for a compact soundbar speaker module driven by a digital audio processor. Two 10 W channels provide enough output for many compact stereo or multi-driver arrangements while the digital input permits direct integration with modern audio pipelines. The bridged Class-D topology supports efficient conversion of digital source audio into speaker power, but external LC speaker filtering and EMI control may still be required according to the manufacturer reference design. Soundbar placement can place the amplifier close to sensitive wireless or microphone circuitry, so switching-current return paths and radiated-emissions testing are essential during hardware validation.

ڈیزائن نوٹس
Use the official TAS5717PHP land pattern and exposed-pad instructions from the current TI datasheet rather than deriving them from the generic HTQFP name. Place the required input, output, and bypass connections according to the manufacturer reference design. The supplied excerpts do not identify individual pin assignments, component values, or the exposed-pad connection, so those details are intentionally not inferred here. A prototype should not be sent for layout fabrication until every connection has been checked against the revision-controlled TI documentation.
Evaluate continuous stereo power at the lowest intended supply voltage and the highest expected ambient temperature. The device is rated for 2 x 10 W, but the verified data does not include theta-JA, theta-JC, maximum junction temperature, or the thermal test configuration. Therefore, no power-dissipation estimate can be stated reliably. Use the manufacturer thermal model, actual copper area, enclosure conditions, and nearby heat sources during validation; do not treat the 10 W headline rating as independent of thermal constraints.
Treat the bridge-tied Class-D outputs as high-current switching nodes. Keep output loops compact, follow the reference layout, and verify whether external speaker filtering is required for EMC or EMI reasons. Do not connect either bridged speaker output to system ground; doing so can short the bridge under common-mode conditions. Chassis and shield grounding should be designed separately from the amplifier output return, with radiated and conducted emissions measured in the final enclosure and cable configuration.
The verified operating supply range is 4.5 V to 26 V, but the supplied excerpts do not identify PVDD limits separately from the digital interface supply. Confirm rail names, tolerances, sequencing, startup behavior, and undervoltage thresholds in the TI datasheet. Decoupling and power-supply sizing must use the amplifier's actual average and transient current rather than output power alone, especially because the Class-D output stage draws current from the supply while delivering power differentially into the speaker load.
