TAS5719PHP - 15W Stereo Class-D Amplifier | Texas Instruments
MPN: TAS5719PHP ✓ فعالTAS5719PHP جائزہ
A Class-D audio amplifier is a switching power amplifier that uses pulse-width modulation to deliver speaker output more efficiently than a conventional linear audio amplifier. The hierarchy is digital audio power amplifier to Class-D amplifier to audio amplifier IC, while the TAS5719 also integrates headphone-driver and signal-processing functions. This combination supports compact consumer and industrial audio systems requiring digital sources and analog speaker outputs.
The principal features are 2 x 15 W stereo output capability, a 4.5 V to 26 V power-supply range, digital audio input, and an integrated capacitor-free headphone amplifier. Its 48-pin HTQFP package supports surface-mount assembly and thermal management through the exposed thermal pad. The device accepts wide-ranging input data and data rates for straightforward connection to digital audio processors and MPEG decoders.
Internally, one serial data input supplies two independently routable discrete audio channels. The digital data path allows channels to be processed before conversion to the power-amplifier stage, reducing the need for a separate analog preamplifier in compatible systems. The integrated capacitor-free headphone path provides an additional low-power analog output function without requiring the traditional series output capacitors used with many headphone drivers.
Typical uses include compact stereo speakers, audio docking stations, consumer television equipment, portable entertainment products, and industrial sound systems. The 15 W per-channel output rating is appropriate for small bookshelf speakers and multimedia speaker systems, while the 4.5 V to 26 V supply range accommodates systems powered from external adapters or higher-voltage industrial rails.
PCB design should prioritize the exposed thermal pad, clean speaker-output routing, stable supply bypassing, and careful return-current management around the switching power stage. Speaker outputs carry high-frequency PWM energy, so keep sensitive audio inputs and external microphone circuitry away from the output nets. Verify thermal performance and EMI behavior in the final enclosure and load configuration.
This page consolidates the verified manufacturer and distributor information, same-package family alternatives, package details, sourcing guidance, and application-specific design considerations. It distinguishes documented electrical facts from parameters that still require confirmation from the manufacturer datasheet before a new PCB or production release.

Compact Stereo Multimedia Speakers
The TAS5719PHP fits compact multimedia speakers requiring 15 W per channel from a digital audio source. It combines a stereo Class-D speaker path, one serial data input, and an integrated capacitor-free headphone amplifier in a 48-pin HTQFP package. Placing the device directly downstream of a digital audio processor eliminates a separate input-routing stage when the source format is compatible. The 4.5 V to 26 V operating range supports several external-adapter architectures, although the final continuous power depends on speaker impedance, PCB thermal performance, and output filtering.

Audio Docking Stations
The TAS5719PHP is well suited to audio docking stations that need both amplified speakers and a headphone connection from a digital source. Its 15 W per-channel Class-D output provides useful power for compact desktop speakers, while the integrated capacitor-free headphone amplifier can reduce the external component count of a conventional headphone stage. The 7 mm by 7 mm HTQFP package supports dense portable-equipment layouts. Firmware and hardware integration must confirm that the incoming serial-audio format, sample-rate range, clocking, and control-register map match the selected processor.

Consumer Television Audio
The TAS5719PHP can provide efficient stereo amplification for compact television and monitor speakers where board space is constrained. Its digital serial input can accept audio directly from a compatible TV audio processor, and the rated 15 W per channel is appropriate for compact internal speakers. The 4.5 V to 26 V supply range supports system-level amplifier rails, while the exposed thermal pad in the HTQFP package enables heat transfer into the PCB. Thermal qualification must reflect the television enclosure, ambient temperature, speaker impedance, and sustained program audio rather than short-duration peak output.

Portable Entertainment Systems
The TAS5719PHP is applicable to portable or compact entertainment products that combine digital audio playback with stereo speakers and headphones. Class-D amplification supports efficient conversion from digital source data to speaker drive, while the integrated capacitor-free headphone path provides a second output mode. A 48-pin HTQFP footprint reduces board area compared with larger discrete amplifier arrangements. Battery-powered designs must include current and thermal analysis across playback volume, because the 15 W rating is a maximum output capability rather than a guaranteed continuous operating point for every supply voltage and speaker load.

Industrial Sound-Control Systems
The TAS5719PHP can amplify stereo program audio in industrial control, panel, or announcement equipment where a digital audio processor drives the sound system. Its 4.5 V to 26 V supply range is useful for 24 V-oriented industrial architectures, subject to the exact regulator and transient requirements. The 15 W per-channel rating supports compact full-range speakers without a large linear amplifier. Because this is a switching power stage, layout should minimize high-current loop area, use a low-impedance ground return, and separate sensitive microphone or sensor inputs from the speaker outputs to limit EMI coupling.
تجویز کردہ
Professional Audio Interface Speakers
The TAS5719PHP suits compact powered speakers that receive digital audio from a central processor or network audio source. A single serial input can route two discrete channels, reducing analog distribution between source and amplifier when the data format is supported. At up to 15 W per channel, it targets smaller monitor or installation speakers rather than high-power professional monitors. Designers should evaluate THD+N, output-filter selection, thermal margin, and electromagnetic emissions in the finished enclosure. The verified 0 C to +85 C operating range supports many indoor industrial and commercial environments.

ڈیزائن نوٹس
Use the exposed thermal pad as the primary heat path and follow the manufacturer's land pattern for vias, copper area, solder-mask, and paste. Because the verified operating range reaches 85 C, calculate worst-case junction temperature at the highest ambient temperature and continuous 15 W-per-channel operating condition. Include the actual speaker impedance, supply voltage, amplifier efficiency, and output-filter loss in the estimate; short promotional output peaks should not be treated as a continuous thermal design point.
Route the Class-D speaker outputs as short, tightly coupled output nets and keep the switching-current loop within the power stage and decoupling network. Do not place sensitive microphone, analog input, or clock traces beneath or parallel to speaker outputs. Use a continuous ground reference where permitted, maintain the datasheet-recommended input and output filter topology, and verify component placement against the manufacturer layout guidance before EMI testing.
Separate amplifier supply planning into the high-current power rail and any lower-voltage digital interface rail, then apply the exact pin-specific voltage and decoupling requirements from the manufacturer datasheet. A 4.5 V to 26 V input range does not mean every supply combination is valid for every output-power or data-rate condition. Check startup sequencing, supply transients, regulator headroom, and the quiescent-current contribution before assigning the 4.5 V minimum to a shared system rail.
Do not substitute a same-package amplifier solely because it is also a Class-D audio IC. Before using TAS5717PHPR, TAS5711PHP, TAS5705PHP, TAS5703PHP, or TAS5702PHP as a substitute, verify every pin, exposed-pad connection, digital data format, sample rate, clock requirement, I2C address, control-register map, speaker output topology, output-filter value, and thermal condition. The alternatives are family-level drop-in candidates rather than automatic approvals.

The supplied verified search results did not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields therefore remain unknown rather than being inferred from the manufacturer or package.
