TAS5028PAG - 8-Ch Digital Audio PWM Processor | TI
MPN: TAS5028PAG ✓ NakahandaTAS5028PAG Ulas
A digital audio PWM processor is a mixed-signal audio IC that accepts digital audio information and generates PWM control signals for a multichannel power-amplifier design. Within the broader semiconductor hierarchy, it belongs to the audio special-purpose IC category, connects digital audio processing with an external amplification stage, and ultimately supports loudspeaker or headphone drive systems. Its eight-channel architecture consolidates parallel audio-channel control into one integrated device.
The principal verified feature is support for eight PWM channels in one 64-TQFP package. According to the Texas Instruments TAS5028 product information, the device automatically adjusts its control configurations and is designed to interface seamlessly with most audio digital signal processors. This integration can simplify system partitioning by moving repetitive PWM generation away from a host DSP and into a dedicated companion processor.
The package and ordering information identify TAS5028PAG as the PAG package option with 64 pins and a 10 mm by 10 mm body. That relatively high pin count provides dedicated external connections for multiple channels and associated control functions. Because the verified search results do not expose the complete electrical limits, detailed pin assignments, signal timing, or performance graphs, those values should be confirmed in the manufacturer datasheet before final schematic, layout, or signal-integrity work.
Typical uses include multichannel active speaker systems, soundbars, home-theater receivers, powered speaker crossovers, compact consumer audio products, and other multichannel digital-audio designs. In these applications, the TAS5028PAG can receive processed audio information from a digital signal processor and produce the PWM signals required by an external bridge-style power stage.
The primary design consideration is to treat the PWM outputs as high-current, fast-transitioning signals and preserve a clean return path from the external amplifier stage. Layout should follow the manufacturer guidance for decoupling and output routing, while the system designer should verify thermal performance and EMI behavior with the selected power-stage topology.
This page combines the verified manufacturer identification, package information, distributor availability, observed pricing, and documented cross-reference findings. It also adds drop-in candidate analysis, application guidance, comparison parameters, and practical design cautions that are not consolidated on a standard distributor listing.

Tipikal na mga Gamit

Powered Soundbar Speaker Arrays
The TAS5028PAG fits an eight-channel powered-soundbar architecture because it integrates digital audio PWM processing for 8 output channels while occupying one 64-pin TQFP. The device can sit downstream of an audio DSP and upstream of an external power-amplifier stage, reducing the need for repeated PWM-generation logic in the host processor. Its 10 mm by 10 mm package supports compact board layouts, although the verified 0 °C to 70 °C operating range should be checked against the enclosure environment. Designers must also preserve short, well-controlled PWM paths and provide the decoupling and grounding specified by the manufacturer datasheet.
Inirekomenda
Multichannel Home-Theater Amplification
The TAS5028PAG is suitable for home-theater receiver and amplifier subsystems requiring eight coordinated digital-audio PWM outputs. Its 8-channel organization maps cleanly to speaker channels, while the dedicated processor role separates PWM control from the main audio DSP workload. The 64-pin TQFP exposes substantially more connections than a small mixed-signal package, which is useful when channel control, clocking, data, and auxiliary functions must be routed separately. Before layout, verify the exact PWM timing, interface format, and supported sampling rates in the current datasheet, then keep amplifier outputs away from sensitive control and return paths.
Inirekomenda
Digital Speaker Crossover Networks
The TAS5028PAG can support an active digital crossover that drives multiple speaker bands from one digital audio source. Eight PWM channels allow the system to allocate separate outputs for low-, mid-, and high-frequency sections, with the external DSP performing crossover filtering before the TAS5028PAG handles modulation. Its 8-channel integration reduces the number of discrete audio-control blocks on a complex network. The design remains sensitive to output trace impedance, grounding, and switching EMI, so power-stage placement, current return paths, filtering, and thermal verification must be planned together rather than treated as a final-board afterthought.
Inirekomenda
Compact Active Speaker Systems
The TAS5028PAG is appropriate for compact active speakers where multiple amplified channels are required without reproducing eight separate PWM-control functions. A digital audio DSP can provide filtering, volume control, and source processing, while the TAS5028PAG supplies the 8-channel PWM control layer in a 64-pin TQFP. The package size of 10 mm by 10 mm supports denser assemblies than many large leaded packages, but exposed-pad, via, and thermal-layout requirements remain package-specific. Verify the 0 °C to 70 °C range against the speaker enclosure and confirm that the selected external amplifier topology accepts the device's documented PWM signals.
Inirekomenda
Multichannel USB Audio Products
The TAS5028PAG can be used in a USB-based multichannel audio product when the upstream controller or codec delivers compatible digital audio data and the downstream design requires eight PWM outputs. Its dedicated 8-channel PWM processor reduces real-time channel-control burden on the USB audio interface. The 64-pin TQFP provides enough physical connections for a multi-signal device, while the 10 mm by 10 mm outline permits integration near the amplifier section. Engineers should isolate USB data, clock, and return paths from fast PWM outputs, validate ground continuity under simultaneous channel switching, and confirm all interface timing against the manufacturer documentation.
Inirekomenda
Professional Multiway Monitor Speakers
The TAS5028PAG fits professional monitor speakers with several independently driven transducers when the source system already performs digital crossover processing. Eight PWM channels provide a practical channel count for a multiway monitor, and the processor can work downstream of a digital audio DSP while driving external power stages. Because the stated operating range tops out at 70 °C, industrial or high-temperature installations require an enclosure-temperature check or an appropriately qualified alternative. The layout should minimize PWM loop area, preserve quiet analog and logic references, and include filtering and test points that make channel verification easier during production.

Talaan ng Disenyo
Route the eight PWM outputs as short, controlled traces directly toward the external amplifier inputs. These signals switch rapidly and can couple into adjacent clock, data, and return paths; keep the output region physically separated from sensitive audio and control nets. Use a continuous ground reference beneath the device where the package design permits, and route output return currents without sharing narrow paths with digital signals.
Follow the manufacturer datasheet for input, output, and internal supply decoupling rather than selecting capacitors from generic audio guidance. Place required ceramic capacitors at their specified pins with minimal loop inductance, and verify that the external amplifier and TAS5028PAG share an appropriate low-impedance return arrangement. Incorrect reference grounding can convert common PWM current into signal error even when the digital waveform itself is correct.
Do not infer the complete pinout or maximum electrical ratings from the 64-pin TQFP package alone. The verified results establish the package and 8-channel function but do not provide the numbered pin table, absolute maximum ratings, supported data format, or timing constraints. Validate those details in the current Texas Instruments datasheet before schematic release and compare every candidate drop-in against those limits.
Treat simultaneous switching across all eight channels as a common-mode EMI and power-supply disturbance event. Evaluate amplifier supply current steps, local reservoir capacitance, output-filter requirements, connector return paths, and enclosure shielding with the final channel loading. Test radiated and conducted emissions at maximum playback or test-signal conditions because a design that behaves correctly with one active channel may exhibit different noise when all eight outputs operate together.
