TAS5727PHP - 25W Stereo Class-D Audio Amplifier | TI
部品番号: TAS5727PHP ✓ 生産中TAS5727PHP 概要
A Class-D audio power amplifier is a switching power amplifier whose output transistors operate at high frequency, allowing higher efficiency than a traditional linear amplifier. Within the broader hierarchy, TAS5727PHP is a digital-input audio power amplifier, a Class-D amplifier, an audio amplifier IC, and a power-management semiconductor designed to reproduce low-power digital audio signals at speaker-driving power levels.
The primary features of TAS5727PHP include 25 W stereo output capability, an 8 V to 26 V PVDD range, digital signal input, integrated EQ and DRC, and low-RDS(ON) output stages that improve thermal performance. Its digital signal path can accept multiple data rates and route two discrete audio channels, allowing integration with digital audio processors, MPEG decoders, and other source devices.
The architecture combines a digital audio input interface with a high-efficiency Class-D output stage. BTL operation permits a speaker to be driven differentially between two output nodes, increasing useful voltage swing into the load. Because the amplifier uses an open-loop digital input architecture, its processing behavior is configured through the associated digital control and configuration method rather than conventional analog feedback around the power stage.
Typical uses include powered speakers, compact stereo audio systems, soundbars, wireless speaker enclosures, home-theater equipment, and consumer products that require local amplification of a digital audio stream. The 48-pin surface-mount package supports compact layouts, while the low-RDS(ON) output design addresses heat dissipation in continuously operating audio equipment.
Designers should account for the amplifier's thermal dissipation, power-supply current, speaker impedance, PCB copper area, and output-filter requirements. The 8 V to 26 V supply range leaves less headroom than higher-voltage power amplifiers, so supply planning is essential when driving 4 ohm loads or sustained high-level audio.

主な用途
TAS5727PHP の用途: 6 件s: Powered Stereo Speakers, Wireless Speaker Enclosures, Soundbar Audio Outputs, Home-Theater Speaker Drivers, Digital Audio Dock Systems, Portable Audio Systems.
Powered Stereo Speakers
TAS5727PHP fits powered stereo speakers because it combines a verified 25 W output rating with a digital audio input and two-channel Class-D output. Each bridge-tied output can drive an 8 ohm speaker, with 4 ohm loads also supported when the power, current, and thermal limits are acceptable. The 8 V to 26 V PVDD range accommodates compact consumer power systems, while the low-RDS(ON) output reduces conduction loss. Designers should size the supply for sustained two-channel audio and preserve thermal performance with the package's exposed-pad copper area.
おすすめ
Wireless Speaker Enclosures
The TAS5727PHP is suitable for wireless speaker enclosures that receive decoded digital audio and drive passive speakers locally. Its 25 W stereo capability offers useful output power for compact household speakers, while the 8 V to 26 V supply range can align with internal bus voltages common in battery-powered and AC-adapter designs. Integrated speaker EQ and DRC provide useful signal conditioning for limiting excessive level differences. A critical design task is maintaining adequate battery or adapter capacity for transient Class-D current while controlling heat around the 48-pin HTQFP package.
おすすめ
Soundbar Audio Outputs
TAS5727PHP can provide the powered left and right channels of a compact soundbar while accepting a common digital audio stream. The two-channel 25 W rating supports stereo reproduction, and programmable routing allows up to two discrete channels to be handled by the device. Its Class-D efficiency is valuable in space-constrained enclosures where heat must be removed without a large heatsink. The system designer should verify channel routing, EQ/DRC configuration, and output-filter component selection for the intended speaker impedance before releasing production hardware.
おすすめ
Home-Theater Speaker Drivers
TAS5727PHP can amplify digital-audio program material for powered home-theater speakers requiring 25 W stereo output. The 8 V to 26 V operating range gives flexibility across external supply architectures, and BTL output avoids requiring a grounded speaker connection if the system uses a suitable isolated output filter arrangement. Integrated EQ and DRC can support speaker protection and program-level consistency. Before selecting it for a passive surround speaker, engineers should calculate amplifier dissipation, verify that the 4 ohm capability is required rather than assumed, and confirm that all digital-control functions match the source processor.
おすすめ
Digital Audio Dock Systems
TAS5727PHP is appropriate for a digital docking system that accepts compressed or linear PCM audio from a host processor and powers local speakers. Its digital input avoids the need for an analog-to-digital conversion stage inside the amplifier, while programmable EQ and DRC help compensate for enclosure and speaker variation. The 25 W output rating provides adequate headroom for many compact two-way speakers. Product developers should validate the supported data rate and word format, configure protection limits correctly, and provide a power supply with sufficient transient-current capability for both channels.
おすすめ
Portable Audio Systems
TAS5727PHP can serve compact portable-audio systems that include local speaker amplification and operate from a regulated supply within the 8 V to 26 V range. The device's Class-D output stage offers high conversion efficiency, while its 48-pin HTQFP package preserves board area. Two-channel output allows separate left and right drivers, and the integrated EQ/DRC functions support consistent playback levels. For battery-based products, designers must evaluate average and peak supply demand, thermal dissipation at the 25 W rating, and whether the system's available bus voltage can sustain the required output without entering protection.

設計ノート
Class-D efficiency reduces average heat, but sustained two-channel playback still requires careful attention to the HTQFP exposed-pad connection. Estimated: with a 20 V supply and 25 W delivered to each 8 ohm channel, output power is 50 W total, although exact device dissipation also includes switching and quiescent losses. Use the manufacturer thermal data for the final junction-temperature calculation and provide continuous copper area to the package ground pad.
Size the PVDD source for the required audio output and the amplifier's transient demand rather than average headphone-style current. Estimated: 25 W at 20 V is 1.25 A for one channel, or 2.5 A for two channels, before allowing for output-stage loss and supply margin. The 8 V to 26 V operating range does not guarantee the 25 W rating at every supply voltage, so verify the output-power curve against the minimum available PVDD.
Place the input, supply, ground, and output-filter connections using the manufacturer reference layout. Keep the exposed thermal pad connected to the ground plane with a low-impedance via array, and provide low-inductance PVDD and ground planes because Class-D output current changes rapidly. Confirm the output filter component values and land pattern against the revision-B datasheet before PCB release.
Do not assume that a 48-pin HTQFP candidate is pin-compatible solely because its package matches. Check every power pin, ground connection, serial-data interface, configuration pin, exposed-pad connection, and output-filter connection. Also verify whether the alternative uses the same data format, clocking method, EQ/DRC implementation, and boot sequence. This check is especially important for TAS5731PHPR and TDA7492, whose detailed compatibility data was not present in the supplied sources.
