TAS5186DDV - 6-Channel 210W Class D Power Stage | TI
部品番号: TAS5186DDV ✓ 生産中TAS5186DDV 概要
A Class D power stage is an audio-amplifier output circuit that switches its supply rails at high frequency to produce a filtered audio waveform. It belongs to the amplifier IC hierarchy, where a digital-input power stage removes the need for external analog audio-input circuitry when it is paired with a compatible audio codec or digital-audio processor. Its principal advantages are high conversion efficiency, compact implementation, and integration of speaker-output protection.
The TAS5186DDV provides six independent amplification channels for multichannel audio systems. Its published performance includes 105 dB A-weighted signal-to-noise ratio, THD+N below 0.05% at 1 W, and efficiency above 90% into recommended loads. Integrated protection covers undervoltage, overtemperature, overload, and short-circuit conditions, reducing the amount of discrete protection required around each speaker output.
Digital inputs allow the amplifier to receive audio samples directly from an audio codec, DSP, or other digital-audio source. This architecture supports a compact signal chain and accurate channel synchronization. The 44-terminal HTSSOP package also provides a practical surface-mount footprint for multi-channel consumer and professional audio equipment, subject to careful thermal and layout design.
Typical uses include powered speakers, soundbar amplifier boards, home-theater receiver power stages, active subwoofer systems, and compact multimedia speaker designs. Its six-channel architecture is particularly useful when one board must drive multiple surround-sound channels without implementing six separate discrete amplifier circuits.
Designers should follow the manufacturer layout guidance for high-current speaker and power-ground paths, place the required decoupling capacitors close to the device, and verify copper area for thermal dissipation. Thermal performance depends on output power, channel utilization, load impedance, PCB copper, and ambient temperature, so a compact enclosure should be validated under worst-case multichannel conditions.
This page combines the device's principal performance specifications, application guidance, design cautions, and identified pin-compatible family options for faster engineering selection. Use the manufacturer datasheet pin-description table and recommended application circuit when assigning PCB nets and confirming thermal limits.

主な用途
TAS5186DDV の用途: 6 件s: Powered Bookshelf Speakers, Home-Theater Amplifier Board, Soundbar Speaker Amplification, Active Subwoofer Power Stage, Digital Audio Speaker System, Portable Multimedia Speaker.
Powered Bookshelf Speakers
The TAS5186DDV fits a powered bookshelf speaker requiring multiple amplified channels and digital audio input. Its six-channel architecture can support left, right, center, surround, and additional drivers without six separate output devices, while the 210 W total rating provides useful channel-power headroom. The 105 dB A-weighted SNR helps preserve low-level detail in quiet passages, and THD+N below 0.05% at 1 W supports clean mid-volume operation. A compact enclosure requires careful PCB copper and thermal validation because sustained multichannel load raises dissipation.
おすすめ
Home-Theater Amplifier Board
The TAS5186DDV is appropriate for a home-theater power stage that must drive multiple surround-sound channels. Six integrated Class D outputs reduce the board area required by discrete amplifier solutions, while digital inputs support a codec-to-amplifier signal path. The device's 10.8 V to 13.2 V supply range suits a nominal 12 V architecture, but rail tolerance and transient headroom must be included in system design. Its 105 dB A-weighted SNR is useful for cinema playback, and integrated overload, short-circuit, undervoltage, and thermal protection provide baseline speaker-rail safeguards.
おすすめ
Soundbar Speaker Amplification
A soundbar amplifier board benefits from the TAS5186DDV's six-channel output in a single 44-terminal HTSSOP package. The digital input architecture shortens the analog path between an audio processor and the Class D outputs, and the device can drive several drivers used by left, right, center, surround, or bass functions. Its 210 W total rating provides flexibility for channel allocation, while greater than 90% efficiency at 1 W reduces power loss in the output stage. Soundbar enclosure cooling remains critical, particularly when several channels operate simultaneously at substantial output power.
おすすめ
Active Subwoofer Power Stage
The TAS5186DDV can form part of an active subwoofer or multi-driver bass amplification system using one or more of its six Class D channels. Its 60 W-class channel capability is relevant for compact speaker designs, while the 210 W total device rating allows flexible use of several channels. The 105 dB A-weighted SNR supports low background noise, and integrated short-circuit and overload protection are valuable around speaker wiring. Because bass transducers can demand sustained high current, the PCB must use short, wide output paths and adequate copper area, and thermal performance must be tested at the lowest intended speaker impedance.
おすすめ
Digital Audio Speaker System
The TAS5186DDV is well suited to a fully digital speaker system in which an audio codec or DSP delivers digital samples directly to the Class D power stage. This architecture avoids carrying high-level analog audio across much of the board and supports controlled channel synchronization. Six outputs can serve multiple drivers, while the 10.8 V to 13.2 V operating range allows use in a nominal 12 V system. The designer must match digital-interface timing and filtering to the source, validate the full data path for dropout behavior, and follow the manufacturer grounding and output-filter recommendations.
おすすめ
Portable Multimedia Speaker
The TAS5186DDV can support portable multimedia equipment when its 10.8 V to 13.2 V supply requirement is compatible with the system battery and converter design. The six-channel output reduces the number of separate amplifier packages required for compact speakers, and Class D efficiency helps limit conversion loss. Its digital input interface can simplify connection to a portable media processor, while 105 dB A-weighted SNR preserves quiet-playback performance. A portable enclosure limits copper area and passive cooling, making thermal simulation and sustained-load testing essential rather than relying only on the 210 W aggregate rating.

設計ノート
Validate thermal performance with all intended channels loaded rather than relying on the 210 W aggregate rating. Use the lowest supported speaker impedance and the highest sustained output expected in production. Provide uninterrupted PCB copper beneath and around the 44-HTSSOP, minimize thermal barriers, and test the assembled board inside its enclosure. If the enclosure prevents convection, increase copper area or add a thermal solution without compromising the recommended high-current layout.
Route speaker outputs, supply rails, and power returns as short, wide paths to reduce voltage drop and electromagnetic radiation. Place input, output, and supply-decoupling capacitors at the locations shown in the manufacturer application circuit, with particularly low loop area between each output stage and its local supply connection. Avoid narrow necks between the amplifier, power supply, and speaker connectors, and keep switching-current paths away from digital-audio traces.
Follow the manufacturer datasheet for exposed-pad or thermal-pad connection and keep high-current outputs away from sensitive clock and audio-data nets. Maintain a continuous return reference beneath digital and analog input routing, use point-to-point digital connections where recommended, and verify that the digital-audio source and amplifier agree on clocking, data format, and channel mapping. PCB changes should be validated for bit errors across voltage and temperature limits.
Do not equate a 44-HTSSOP footprint with unconditional drop-in compatibility. Before substituting TAS5186ADDVR, TAS5186DDVR, TAS5186DDVRG4, TAS5186DDVG4, or TAS5176DDWR, compare pin names, exposed-pad requirements, control signals, digital timing, output filtering, protection behavior, and electrical limits. Also confirm that the supply rail remains between 10.8 V and 13.2 V under load and that startup order matches the audio source.
