TAS5760LDDCA - 21W Stereo I2S Class-D Amplifier | TI
The Texas Instruments TAS5760L (orderable as TAS5760LDDCA) is a digital-input Class-D audio amplifier delivering 21 W per channel in stereo or 42 W mono from a 4.5 V to 16.4 V supply, housed in a 48-pin HTSSOP PowerPAD package with exposed die-attach pad. 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.

TPA3116D2DADR - 50W Stereo Class-D Audio Amp | Texas Instruments
The Texas Instruments TPA3116D2DADR is a filter-free, analog-input Class-D stereo audio amplifier delivering 2 x 50 W into 4-ohm speakers (or 100 W mono BTL into 2 ohms) from a 4.5 V to 26 V supply, packaged in a 32-pin HTSSOP (DAD) with exposed thermal pad. A Class-D audio amplifier is a switching amplifier whose output transistors operate as switches rather than linear elements, achieving efficiency above 85-90 percent. In the amplifier IC hierarchy, it sits under audio amplifiers, within the broader linear-amplifier IC family, and replaces bulky Class-AB stages plus heat sinks in compact speaker systems. Key features include filter-free operation with an integrated feedback loop that tolerates speaker inductance without an LC output filter, SpeakerGuard amplitude limiting that protects speakers from over-power events, and an AM-avoidance modulation scheme that keeps switching harmonics out of the AM broadcast band. Differential analog inputs improve common-mode noise rejection, and integrated short-circuit and thermal shutdown protection raise system robustness. The device uses an AD modulation topology with 250 kHz-class switching, so high efficiency eliminates heat sinks in most 2 x 50 W designs on a two-layer PCB with adequate copper pour. Fixed internal gain options and a master/slave-capable architecture simplify multi-channel designs; power-supply pumping is managed by the BTL configuration at low frequencies. Typical applications include Bluetooth and active speakers, soundbars, TV audio, portable PA and karaoke systems, and automotive/infotainment speaker drivers where efficiency and small size matter. Design consideration: at 2 x 50 W, PCB copper area under the exposed pad is the primary thermal path - provide a solid ground pour with thermal vias, and place supply decoupling (at least 10 uF bulk plus 0.1 uF ceramic) close to PVCC pins to minimize supply ripple and EMI.
