TAS5760LDDCA 概要
A Class-D audio amplifier switches output power MOSFETs at high frequency to amplify an audio signal with high efficiency, in contrast to Class-AB linear amplifiers that dissipate substantial power as heat. Within the power-management and audio signal-chain hierarchy, the TAS5760L is a closed-loop digital-input speaker amplifier: it accepts an I2S/TDM serial audio stream, performs digital signal processing and PWM modulation on-chip, and drives speakers directly through an external LC filter or filterless output network.
Key features include a wide 4.5 V to 16.4 V operating supply range, 21 W stereo / 42 W mono output capability, both hardware and software (I2C) control modes, an integrated digital clipper that protects speakers from overdrive, several selectable gain settings, and integrated headphone/line-output support. Two clock speed modes let designers match a variety of audio master-clock configurations without regenerating the audio stream.
Technically, the TAS5760L integrates the full path from digital audio input to power stage: serial-port receiver, audio processing, PWM modulator, gate drive, and power FET H-bridges. The digital clipper acts before the power stage, so clipping artifacts are managed in the digital domain. The entire TAS5760xx family is pin-to-pin compatible in the 48-pin TSSOP package, per TI product documentation.
Typical applications include TV soundbars, portable and desktop speakers, LCD TV audio, and docking/foundation systems where an I2S source drives speakers directly without a separate DAC. The wide supply range supports both battery and adapter-powered designs.
Design-wise, provide a low-impedance PVDD supply with bulk and local decoupling, and size the LC output filter for the selected PWM switching frequency; thermal design relies on a good PowerPAD solder connection to the PCB copper plane.

主な用途
TAS5760LDDCA の用途: 6 件s: TV Audio Systems, Soundbars, Portable and Desktop Speakers, Home Theater Receivers, Docking and Foundation Audio Systems, Consumer Audio Appliance Amplifiers.
TV Audio Systems
The TAS5760L suits LCD TV audio because its I2S digital input connects directly to the TV SoC without an external DAC, reducing component count and preserving signal quality end to end. With 21 W per channel stereo output from a 4.5 V to 16.4 V supply, it covers typical TV speaker power levels on a single 12 V rail, and the integrated digital clipper limits overdrive on small, excursion-limited TV speakers. The integrated headphone/line driver in the 48-pin package lets one device serve both internal speakers and an external line output. Designers should place the output LC filter close to the device and follow the TI datasheet filter values for the chosen PWM frequency.
おすすめ
Soundbars
Soundbar designs benefit from the TAS5760L's digital I2S input, which accepts audio directly from an HDMI-switch or streaming SoC without analog conversion, keeping the signal path clean from source to speaker. Its 42 W mono (bridged) capability supports higher-output center channels, while stereo 21 W channels handle left/right arrays, all from a 4.5 V to 16.4 V supply compatible with common external adapters. Multiple gain options let one PCB serve several soundbar power tiers. Verify LC filter sizing per the TI datasheet for the target load impedance and enclosure, and use the digital clipper settings to protect compact long-throw drivers from clipping damage at high volume.
おすすめ
Portable and Desktop Speakers
For battery- or adapter-powered speaker docks, the TAS5760L's wide 4.5 V to 16.4 V supply range allows the same PCB to ship in both 5 V battery and 12 V adapter configurations, simplifying platform logistics. The I2S input pairs naturally with wireless audio SoCs that output digital audio directly, eliminating a DAC and its associated noise and BOM cost. The two clock speed modes accommodate different audio master-clock configurations from the source device. Designers should size the output filter inductors for the selected speaker impedance and confirm thermal performance with the exposed PowerPAD soldered to a copper plane per the TI datasheet layout guidance.
おすすめ
Home Theater Receivers
In compact home theater and receiver products, the TAS5760L provides a digitally driven speaker channel from the AV processor's I2S or TDM output, avoiding the noise floor and PCB area of an analog DAC plus amplifier chain. The 42 W mono bridged mode supports demanding center-channel loads, and stereo mode serves satellite channels on the same footprint. Hardware control mode allows channels without a host MCU to configure gain via pins, while I2C software mode integrates with system-level volume and EQ control. Follow the TI datasheet recommended decoupling on PVDD and keep high-current PWM loops small to meet consumer EMI requirements.
おすすめ
Docking and Foundation Audio Systems
TI positions the TAS5760xx family for docking and foundation audio applications, where a speaker dock receives digital audio from a phone, tablet, or embedded host. The I2S serial port interfaces directly with the dock's SoC, and the integrated headphone/line driver of the 48-pin device supports a passthrough line output to external speakers or headphones without additional circuitry. The digital clipper protects dock speakers from overdrive at maximum volume, and gain options let the same hardware adapt to different speaker sensitivities. Designers should confirm clock-domain compatibility between host and amplifier using the two speed modes documented in the TI datasheet.
おすすめ
Consumer Audio Appliance Amplifiers
Any consumer product that streams or plays digital audio - smart speakers, kitchen radios, tabletop music systems - can use the TAS5760L as its complete digital-to-speaker power stage. The device eliminates the DAC, analog volume control, and separate amplifier that an analog chain would require, shrinking PCB area and BOM cost. The 21 W stereo output covers the majority of compact consumer speaker power levels, and the wide 4.5 V to 16.4 V input accommodates USB-C, battery, and adapter power sources alike. Use I2C software control to implement volume, mute, and protection behavior from the product's main controller, per the TI datasheet control-mode documentation.

設計ノート
The TAS5760LDDCA uses a 48-pin HTSSOP PowerPAD package whose exposed die-attach pad must be soldered to a PCB thermal pad connected to a substantial copper pour. Class-D amplifiers dissipate heat primarily through conduction losses and output-stage switching losses, and at 21 W per channel the die relies entirely on this pad for heat removal. Follow the TI datasheet PowerPAD mechanical and thermal layout section: use an array of thermal vias from the top-side pad to internal and bottom copper planes. Estimated: insufficient PowerPAD solder coverage is the most common cause of thermal shutdown in TAS576x designs.
Keep the PVDD supply decoupling close to the device: place bulk capacitance and local ceramic capacitors at the PVDD pins to supply the PWM switching currents. Route the high-current Class-D output loops (PVDD to output filter to speaker return) with short, wide traces to minimize loop inductance and radiated EMI. Keep the I2S clock and data lines short and away from the output filter inductors to prevent coupling of switching artifacts into the digital audio input.
Do not reuse a TAS5760L PCB with a non-TAS5760xx substitute: TI states pin-to-pin compatibility only within the TAS5760xx family in the 48-pin TSSOP package, and the 32-pin TSSOP TAS5760 variants are NOT footprint-compatible with the 48-pin device. Also verify that the source SoC's audio clock configuration matches one of the TAS5760L's two supported speed modes before committing to the layout; an unsupported clock ratio will cause audio artifacts despite correct wiring.
