TAS5707PHP - 20W Stereo Class-D Amplifier | Texas Instruments
料号： TAS5707PHP ✗ 停产TAS5707PHP 概述
A Class-D audio power amplifier is a switching power amplifier that converts a digital or analog audio input into a high-efficiency speaker drive signal. Compared with a linear audio amplifier, the Class-D architecture reduces the amount of power dissipated by the output devices, which is valuable in portable and space-constrained equipment. The TAS5707PHP includes integrated audio processing functions that help tailor the output for speaker characteristics and system volume requirements. This combination of digital input, programmable processing, and a 20-W stereo output makes the device useful in speakers, sound bars, television equipment, and other systems requiring local amplification of a digital audio stream.
The verified product description identifies the TAS5707PHP as a 20-W stereo digital audio power amplifier with speaker EQ and DRC. The stereo configuration allows two discrete audio channels to be processed and amplified in a single device, reducing the component count compared with separate mono amplifier channels. The open-loop architecture is also important because it provides a defined signal path that can be integrated with an external audio processor or system controller. The device therefore serves both as a power stage and as a digitally controlled audio subsystem element.
The main engineering tradeoff is that the design must be validated for speaker impedance, power limitations, thermal conditions, and the specific digital audio configuration. The manufacturer product page identifies TAS5707PHP as not recommended for new designs, so it should be selected primarily for existing designs, legacy platforms, or qualified repair and production situations rather than as the default choice for a new product. The 48-pin HTQFP (PHP) package also requires a PCB footprint and land pattern that match the manufacturer package drawing.
TAS5707PHP can be used in compact stereo speakers, television or monitor audio, communication terminals, portable equipment, and other embedded audio products where two amplified channels are needed. Digital audio sources can feed the amplifier through its digital input, allowing EQ and DRC to be configured in the digital processing domain. Designers should confirm the required sample rate, audio-word format, channel count, speaker impedance, power target, and control configuration against the manufacturer datasheet before layout or firmware development.
This product page consolidates the verified TI product description, distributor package information, pricing reference, lifecycle indication, and practical application guidance for engineers evaluating TAS5707PHP. It emphasizes the distinctions that affect a real replacement decision: the 20-W stereo Class-D output, digital-input architecture, integrated speaker EQ and DRC, 48-pin HTQFP (PHP) package, and the manufacturer's not-recommended-for-new-designs status.

典型应用
TAS5707PHP 适用于 6 应用s: Compact Stereo Speaker, Television and Monitor Audio, Communication Terminal Audio, Digital Audio Source System, Portable Audio Device, Legacy Audio Product Maintenance.
Compact Stereo Speaker
The TAS5707PHP fits a compact stereo speaker because it combines a 20-W Class-D output stage with two-channel processing in one 48-pin HTQFP (PHP) package. Its digital input allows the audio source, codec, or host processor to deliver the channel data directly, while integrated speaker EQ and DRC provide system-level control over tonal balance and output level. Compared with a pair of discrete mono amplifiers, the stereo configuration can reduce board area and simplify the audio path. The designer must still confirm speaker impedance and the manufacturer test conditions associated with the 20-W rating. Because TI does not recommend TAS5707PHP for new designs, it is most appropriate when maintaining an existing platform or repairing an established audio product. Verify thermal performance in the final enclosure and provide a stable, low-noise supply before production release.
推荐
Television and Monitor Audio
A television or monitor can use the TAS5707PHP to amplify a digital stereo audio stream into two bridge-tied speakers. Its 20-W stereo rating is relevant to compact speakers mounted close to a display, and the integrated speaker EQ and DRC can be used to manage the acoustic response and output level in a constrained enclosure. The open-loop digital architecture keeps the input path deterministic, which can simplify integration with a system controller. Layout should isolate the switching output stage from sensitive signal and microphone areas, while adequate copper and thermal spreading help the HTQFP (PHP) package dissipate power. Since the verified data does not specify supply limits or supported sample rates, those items must be confirmed from the manufacturer datasheet. The part's not-recommended-for-new-designs status should also be weighed for new display platforms.
推荐
Communication Terminal Audio
The TAS5707PHP is suitable for communication terminals that include a local speaker output driven from a digital audio bus. Two processed channels, a 20-W Class-D output capability, and programmable EQ and DRC provide a compact solution for voice terminals, intercom endpoints, and hands-free monitoring products. The digital interface allows the host to supply separate left- and right-channel data while the integrated processing functions address speaker response and level control. Layout must preserve a short return path for the Class-D power stage and provide adequate input/output decoupling according to the manufacturer guidance. Verify the required audio-word length, sample rate, and control protocol before connecting the source processor. For new communication products, assess whether a currently recommended TI amplifier offers a better lifecycle position while preserving the same system architecture.
推荐
Digital Audio Source System
In a digital audio source system, the TAS5707PHP can sit at the output of a codec, decoder, or digital host and provide efficient power amplification for two speakers. Its open-loop architecture and integrated speaker EQ and DRC make it useful where system software must control the relationship between source content and the connected speaker. The 20-W stereo specification provides a clear starting point for amplifier selection, while the 7 x 7 mm HTQFP (PHP) package supports compact assemblies compared with larger discrete output stages. Firmware and configuration work must be matched to the part's supported serial-audio format, which is not exposed in the verified snippets. Confirm supply sequencing, mute behavior, and protection requirements from the datasheet. Existing designs benefit from these integrated features; new designs should account for the manufacturer's lifecycle recommendation.
推荐
Portable Audio Device
The TAS5707PHP can support portable or battery-powered audio products that require more output power than a small integrated headphone amplifier can provide. The efficient Class-D topology is advantageous in mobile equipment because switching output stages generally reduce dissipation compared with linear amplification, although the actual battery impact depends on the audio duty cycle and load. The device accepts digital audio, allowing a host processor to provide a compact system path, and its EQ and DRC functions can help reconcile speaker limitations with a controlled listening level. Supply voltage, idle current, and thermal rise are not present in the verified data, so battery-life and enclosure studies cannot be completed from this page alone. Use the manufacturer datasheet for those values and evaluate the not-recommended-for-new-designs status before initiating a portable platform.
推荐
Legacy Audio Product Maintenance
TAS5707PHP is particularly relevant to maintenance and continuation of an established stereo audio platform because the TI part-details page states that it is not recommended for new designs. An existing PCB using the 48-pin HTQFP (PHP) footprint can benefit from distributor availability without changing its mechanical layout, provided the ordered device matches the required pinout and device revision. The verified listings show sourcing through DigiKey, Mouser, LCSC, and Rochester Electronics, which provides several potential channels for obsolete or constrained supply. Procurement should still verify lot traceability, date code, and refurbishment status. Engineers should use the manufacturer datasheet and package drawing rather than an aggregator pinout, because the complete pin definitions and exposed-pad requirements are not included in the verified source snippets.

设计说明
Validate thermal performance in the final PCB and enclosure because the verified data provides a 20-W product rating but does not state the test conditions, continuous-power limit, junction temperature, or package thermal resistance. Use the manufacturer SOA and thermal information for the exact supply, speaker impedance, and output waveform. Keep the exposed-pad or thermal interface area unobstructed according to the package drawing, and confirm that copper spreading is appropriate for the board stack-up.
Separate the Class-D switching outputs and their high-current return paths from digital audio inputs, control interfaces, and sensitive analog circuitry. Follow the manufacturer layout and land-pattern guidance exactly, including exposed-pad connections and bypass-capacitor placement. Keep input routing short and away from the power-stage switching nodes to reduce switching-induced noise and the possibility of unstable audio output.
Do not assume that all 48-pin PHP-family audio amplifiers are register-compatible or pin-compatible. For TAS5710PHPR, TAS5713PHP, and TAS5709AGPHPR, verify every power, ground, clock, data, control, and exposed-pad connection against both datasheets. Also confirm the digital serial-audio format, sample rate, channel mapping, speaker impedance, and supported supply range before treating any related device as a substitution.
The available source data does not specify the TAS5707PHP supply-voltage range or quiescent current. These parameters must be obtained from the manufacturer datasheet before designing the power tree, regulator selection, startup sequence, or battery budget. Decoupling values should also follow the datasheet's recommended circuit rather than generic Class-D layouts, especially when the digital audio source and power converter are placed far from the amplifier.
合规信息
The verified source snippets do not provide explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals declarations for TAS5707PHP. These fields remain unknown rather than being inferred.
