STA308A13TR - 8-Channel 24-Bit Audio DSP | STMicroelectronics
부품 번호: STA308A13TR ✓ 활성STA308A13TR 개요
A digital audio processor is a specialized signal-processing IC that operates on digital audio streams rather than directly amplifying an analog waveform. Within the broader hierarchy of DSP, audio DSP, and integrated circuits, it provides channel routing, volume control, equalization, sampling-rate handling, and multichannel processing. These functions are commonly used in home theater, professional audio, automotive infotainment, and powered-speaker products.
The DDX architecture supports eight channels of 24-bit processing with greater than 100 dB SNR and dynamic range. Selectable 32 kHz through 192 kHz input rates provide flexibility for CD-rate, high-resolution audio, and multichannel entertainment sources. Six DSD/SACD input channels extend the digital input capability beyond conventional PCM operation.
Programmable signal conditioning includes digital gain and attenuation from +58 dB to -100 dB in 0.5 dB steps, soft-volume updates, individual channel and master gain controls, and channel trim from -10 dB to +10 dB. Each channel can support up to ten independent 32-bit user-programmable biquad equalizers, allowing tonal correction without changing the external analog signal path.
Typical systems include multichannel A/V receivers, digital active loudspeakers, automotive audio controllers, home-theater processors, and professional sound equipment. The 64-pin TQFP provides enough external connections for multichannel digital audio, control, clocking, and power rails while supporting surface-mount manufacturing.
Designers should preserve the recommended clock, layout, grounding, and decoupling arrangements from the manufacturer datasheet. I2C configuration must account for the selectable device address, while software should handle the soft-volume update sequence to prevent audible gain discontinuities. The processor supports a -40 °C to 90 °C operating-temperature range according to the product listing.
This page combines the available channel-count, bit-depth, SNR, sampling-rate, gain-control, DSD/SACD, package, and temperature information with practical selection guidance. It also distinguishes verified drop-in candidates from related products that cannot be assumed to share pin compatibility.

일반적인 애플리케이션
STA308A13TR 적합 용도: 6 애플리케이션s: Home Theater Audio Processor, Digital Active Speaker System, Automotive Infotainment Audio, Professional Multichannel Mixer, High-Resolution Network Audio Player, Multichannel Digital Speaker Hub.
Home Theater Audio Processor
The STA308A13TR fits a home-theater processing stage requiring eight 24-bit digital-audio channels and support for source rates from 32 kHz to 192 kHz. Its greater-than-100 dB SNR and dynamic range preserve low-level detail in movie and music program material, while soft-volume updates and per-channel trim help balance speakers. The six DSD/SACD inputs add value for high-resolution source compatibility. Integration requires validating serial-audio routing, clocking, latency, and amplifier-channel assignments in the manufacturer datasheet.
추천
Digital Active Speaker System
A digital active loudspeaker can use the STA308A13TR to apply channel-specific gain, attenuation, trim, and equalization before the power-amplifier stage. Eight 24-bit processing channels provide useful flexibility for multiway or multi-room systems, while the greater-than-100 dB SNR protects quiet passages and room-fading transitions. The 32 kHz-to-192 kHz range supports multiple digital-source classes. Designers should account for the processor's processing latency and preserve its recommended layout and decoupling arrangements.
추천
Automotive Infotainment Audio
The STA308A13TR can support centralized digital-audio routing and tone management in an infotainment head unit, where multiple source zones may require independent gain and equalization. Its eight processing channels, six DSD/SACD inputs, and selectable 32 kHz-to-192 kHz sample rates suit demanding multimedia configurations. The -40 °C to 90 °C operating range is relevant to automotive environments, but a production design must still verify electromagnetic, automotive-qualification, supply, and environmental requirements beyond the published operating range.
추천
Professional Multichannel Mixer
The STA308A13TR suits a digital mixing or monitoring architecture that needs per-channel level management and programmable equalization. Up to ten independent 32-bit biquads per channel enable speaker correction, tonal shaping, and crossover-adjacent processing, while master and individual gain controls support straightforward balance control. Digital attenuation spans +58 dB to -100 dB in 0.5 dB increments, and soft-volume updates help manage level transitions. Clock synchronization and channel-latency alignment remain critical in a multi-device studio system.
추천
High-Resolution Network Audio Player
A network or streaming audio player can use the STA308A13TR as the central digital conditioning stage for high-rate PCM and DSD/SACD sources. Selectable 32 kHz-to-192 kHz inputs accommodate several source formats, while six DSD/SACD channels broaden compatibility with premium content. The greater-than-100 dB SNR and dynamic range benefit low-level musical material, and the programmable biquads allow output-path compensation. The implementation should preserve the digital clock domain and use I2C address selection so multiple processors do not conflict.
추천
Multichannel Digital Speaker Hub
The STA308A13TR is appropriate for a hub that receives several digital audio streams and prepares them for powered speaker channels. Eight 24-bit channels, six DSD/SACD inputs, and per-channel gain and equalization allow centralized configuration instead of separate fixed processing blocks. Sample-rate selection from 32 kHz to 192 kHz supports varied source conditions, while soft-volume updates can reduce audible level steps. A practical design must confirm connector routing, supported master-clock arrangements, I2C address selection, and output latency.

설계 노트
Use the manufacturer datasheet's recommended multilayer-board stack-up, grounding plane, and high-speed digital-audio trace routing. Keep clocks and serial-audio signals short, avoid routing them adjacent to switching nodes, and provide continuous return paths beneath signal traces. The TQFP-64 package requires careful fanout from the fine-pitch leads; confirm the selected land pattern and assembly process against the package drawing before releasing artwork.
Apply the datasheet's recommended supply bypassing directly at the appropriate power and ground pins. Separate or minimize the return path of noisy supply currents, and verify the required voltage, tolerance, sequencing, and power-up conditions for every rail. Do not infer operating limits from the package drawing; use the electrical-characteristics tables to select the regulator and decoupling network.
Validate the master clock, serial audio, and control signals for the complete source-to-processor-to-converter chain. Confirm clock ratios, supported sample rates, signal polarity, and expected latency for every operating mode. When multiple processors or converters share timing, budget propagation delay and channel alignment across the system rather than evaluating each device in isolation.
Avoid treating the STA30813TR comparison as proof of unconditional software compatibility with the STA308A13TR. Before substitution, compare every power pin, clock pin, serial-audio pin, I2C pin, ground connection, register, interrupt, reset function, and format support. Also verify biquad resources and volume-control behavior, because these functions affect the amount of host software and recalibration required after replacement.
