TAS5076PFC - 6-Channel Digital Audio PWM Processor | TI
부품 번호: TAS5076PFC ✗ 단종TAS5076PFC 개요
A digital audio PWM processor is an application-specific integrated circuit that accepts digital audio data and generates PWM signals suitable for controlling audio power stages. Unlike a conventional analog audio amplifier, the TAS5076PFC performs digital-to-PWM conversion and associated channel control. It sits between an audio source or digital interface and one or more external Class-D output stages, making it useful in home-theater systems, powered speakers, automotive audio, and professional audio equipment.
The TAS5076PFC provides six-channel PWM processing in a single device, which can simplify system integration compared with a design using multiple discrete or single-channel digital audio converters. Its surface-mount TQFP construction supports automated PCB assembly and high-density equipment designs. The 12 mm by 12 mm body is larger than a typical QFP, but it provides 80 terminals and sufficient routing flexibility for multichannel digital and power-control connections.
As a special-purpose audio processor, the TAS5076PFC is intended for digital signal processing rather than general-purpose computation. Its internal architecture and register interface determine how digital audio data is accepted, distributed across six channels, and converted into PWM outputs. Exact interface timing, supported audio data formats, clock requirements, output characteristics, and control-register functions should be confirmed in the manufacturer datasheet before a circuit is released.
Typical applications include powered home-theater speakers, multichannel amplifier modules, automotive head-unit audio systems, digital active speakers, and professional monitoring equipment. In each case, the processor can provide a coordinated six-channel PWM generation function while leaving the final high-current audio output stage to appropriately rated external hardware. Actual channel implementation depends on the supported digital-audio format and the system amplifier architecture.
The primary design consideration is ensuring that the digital source format, clocking, ground distribution, and PWM routing satisfy the device requirements. Place decoupling close to its supply terminals, route sensitive digital signals over a continuous reference plane, and use the pin-description table in the manufacturer datasheet when assigning PCB tracks. Because the processor does not directly replace a high-power output transistor array, external power stages and their thermal design remain part of the complete amplifier solution.
This product record combines the verified identity of the TAS5076PFC with packaging information, sourcing guidance, and a structured review of what engineers must confirm in the datasheet. It also distinguishes confirmed replacement information from unavailable pin-level, timing, and compliance details, helping designers assess fit before beginning layout or firmware development.

일반적인 애플리케이션
TAS5076PFC 적합 용도: 6 애플리케이션s: Powered Home-Theater Speakers, Multichannel Amplifier Modules, Automotive Audio Head Units, Digital Active Speaker Systems, Professional Audio Monitor Systems, Digital Cinema Amplification.
Powered Home-Theater Speakers
The TAS5076PFC fits multichannel powered-speaker designs because it provides six digital audio PWM channels in one 80-pin TQFP device. It can sit between the speaker's digital audio interface and six external Class-D output channels, reducing the number of separate digital PWM conversion blocks required for a surround or theater configuration. This arrangement keeps digital decoding and control separate from high-current amplification while allowing coordinated channel generation. Confirm supported sample rates, serial formats, clocking, and PWM output requirements in the manufacturer datasheet before assigning channel signals.

Multichannel Amplifier Modules
A six-channel amplifier module can use the TAS5076PFC as its digital modulation stage, with each PWM channel driving the appropriate external power amplifier circuitry. The processor's six-channel architecture is appropriate for compact multichannel modules used in active speakers and rack-mounted audio products. Its 80-pin TQFP package exposes numerous power, ground, digital, and output connections, but that density requires careful partitioning. Keep high-current switching returns away from the processor's quiet signal paths, follow the pin table exactly, and verify thermal performance across the worst-case output power.
추천
Automotive Audio Head Units
The TAS5076PFC's six-channel PWM processing function can support compact multichannel audio architectures in automotive head units and vehicle amplifier modules. Digital audio generation offers a path to reproducible channel control and efficient external Class-D output stages, while the processor handles six channels in a single package. Because the identified temperature grade is commercial, a production automotive design must confirm AEC-Q100 status and temperature limits. System qualification should also cover transient, vibration, temperature, and long-term reliability requirements before release.

Digital Active Speaker Systems
Active speakers can use the TAS5076PFC to convert digital audio information into six PWM drive channels for locally mounted power stages. This is useful in cinema speakers, professional monitors, and networked speakers that receive digital audio rather than conventional line-level analog signals. Six-channel integration can simplify channel synchronization and reduce board area compared with multiple single-channel converters. The selected digital source must match the processor's supported format and clock architecture, and each external power stage must be designed for its required bandwidth, output power, and thermal load.
추천
Professional Audio Monitor Systems
The TAS5076PFC is architecturally suitable for professional monitoring and installed-sound systems requiring several synchronized digital PWM channels. It can provide a common digital modulation stage for multiple external Class-D amplifiers, helping designers centralize channel processing while distributing power amplification across the product. In monitoring applications, clock jitter, channel alignment, and ground contamination directly affect audio performance. Use a clean digital-audio source, implement the manufacturer's recommended decoupling and clock routing, and keep switching-node energy outside the processor's quiet signal return paths.
추천
Digital Cinema Amplification
Digital cinema amplifiers commonly require several high-quality channels with synchronized modulation and centralized digital control. The TAS5076PFC provides six-channel digital audio PWM processing in an 80-pin TQFP package, making it relevant to cinema amplifier electronics with local Class-D output stages. Its role ends at PWM generation; speaker power, switching losses, reconstruction filters, and protection remain external. Validate the complete signal chain against the film's source format, amplifier channel map, latency expectations, and thermal conditions before production deployment.

설계 노트
Use the 80-terminal pin-description table in the manufacturer datasheet as the authority for every PCB connection. Place supply and ground bypass capacitors close to their associated terminals, use uninterrupted ground planes beneath the device, and partition the layout into digital audio, clock, control, and PWM regions. Keep switching-node and high-current output-stage paths away from sensitive digital traces. The verified package dimensions are 12 mm by 12 mm, but those dimensions alone are not a substitute for the land pattern and pin map.
Treat the clock and digital-audio nets as high-speed signals even though their exact timing limits are not stated in the product listing. Use short, matched-length routes where the datasheet specifies timing constraints, provide a continuous reference plane, and avoid routing these nets beneath digital PWM outputs or power-stage switching nodes. Review source drive strength, input capacitance, jitter tolerance, and supported data formats in the manufacturer datasheet. Firmware and hardware must use the same clocking and channel-mapping configuration.
Estimated: the processor's dissipation depends on supply voltage, internal activity, and switching frequency, which are not stated; therefore no defensible junction-temperature calculation can be produced. Measure or estimate the complete amplifier heat budget by separating processor loss from external Class-D output-stage loss. Provide copper area under the TQFP and follow the manufacturer's thermal layout guidance. Use the datasheet operating-temperature and electrical-limit tables to define worst-case conditions for production validation.
Do not assume that the TAS5086 can replace the TAS5076PFC solely because both are six-channel processors in 80-pin TQFP packages. Compare the complete pin table, supply limits, clock architecture, data formats, control registers, PWM behavior, qualification status, and firmware requirements. Likewise, ordering-code variants should not be treated as separate engineering alternatives without confirming their package, temperature grade, and ordering meaning. For a legacy design, preserve the verified MPN and request manufacturing traceability before releasing production quantities.
