STA323W13TR - 2.1-Channel 10V 40W Audio System | STMicroelectronics
부품 번호: STA323W13TR ✓ 활성STA323W13TR 개요
A digital audio system combines digital signal processing, digital amplifier control, and a switching power-output stage in one IC. This integration sits between a digital audio source and loudspeaker outputs, reducing the number of discrete components required in compact home-theater, multimedia, active-speaker, and automotive entertainment systems. The integrated architecture also centralizes gain, modulation, protection, and power-stage control.
The STA323W13TR supports three power-output configurations and accommodates 2.1-channel systems in which a subwoofer channel is combined with two main channels. Its 24-bit processing path provides a 100 dB signal-to-noise ratio and dynamic range, while the 32 kHz to 192 kHz input range covers CD, DVD, broadcast, computer, and modern high-resolution audio sources.
Thermal protection, under-voltage protection, and short-circuit protection are integrated into the device. These safeguards are important because class-D power stages can develop high current during low-impedance loads, supply faults, or output-stage overstress. The PowerSSO-36 package provides an exposed thermal pad for transferring heat into the PCB copper area rather than relying on a separate heatsink in moderate-power designs.
Typical applications include compact 2.1-channel active speakers, home-theater soundbar amplification, multimedia speaker systems, digital active loudspeakers, and embedded audio products. The IC is especially useful when the source already supplies a digital audio stream, because the digital processing and amplifier-control functions reduce the need for a separate codec, preamplifier, and class-D controller.
Designers should confirm the selected output configuration, channel routing, speaker impedance, and allowable power before layout. The exposed pad, input/output capacitors, power-supply decoupling, and thermal copper must follow the manufacturer's reference layout. A thermal estimate should include the regulator dissipation at the actual supply voltage and load rather than relying only on the headline output-power rating.
This product overview combines digital-audio system context, verified electrical highlights, drop-in replacement guidance, and implementation guidance. It is intended to help engineers evaluate power, routing, protection, thermal management, and package constraints before integrating the STA323W13TR into an audio product.

일반적인 애플리케이션
STA323W13TR 적합 용도: 6 애플리케이션s: Compact Home-Theater Soundbar, Powered 2.1-Channel Loudspeaker, Multimedia Speaker System, Digital Active Loudspeaker, Automotive Audio Amplification, Digital Audio Reference Platform.
Compact Home-Theater Soundbar
The STA323W13TR fits a compact 2.1-channel soundbar because it combines digital audio processing, digital amplifier control, and a DDX power-output stage in one 36-pin PowerSSO device. The 24-bit processing path and 100 dB signal-to-noise ratio support low-noise amplification of compatible digital audio streams, while the 32 kHz to 192 kHz input range accommodates common home-theater sources. With a suitable output configuration, the system can reach up to 40 W. The exposed pad requires a deliberate thermal-copper layout because all three channels share the same package and ambient environment.
추천
Powered 2.1-Channel Loudspeaker
A powered speaker can use the STA323W13TR to reduce the number of separate digital-audio and amplifier blocks needed for two main channels and a subwoofer channel. Its three output configurations allow the implementation to be matched to the intended channel arrangement, while the integrated control and output stage reduce board area. The 100 dB dynamic range is useful for reproducing quiet passages without adding excessive system noise. Designers should verify each channel's speaker impedance and simultaneous-load thermal conditions before finalizing the power supply and output network.
추천
Multimedia Speaker System
The STA323W13TR is suitable for desktop and multimedia speaker systems that receive digital audio from a host controller. Its 24-bit DDX processing supports high-resolution digital streams, and the 32 kHz to 192 kHz range covers standard multimedia playback through higher-rate source material. Consolidating processing and amplification into one IC simplifies the signal chain compared with separate digital processing and output-stage blocks. The implementation remains thermally constrained at high output power, so the PowerSSO-36 exposed pad should be tied to a low-impedance thermal-copper structure as specified by the manufacturer.
추천
Digital Active Loudspeaker
In a digital active loudspeaker, the STA323W13TR can combine digital audio handling with the power stage needed to drive the speaker network. The 2.1-channel architecture supports configurations with two full-range channels and one subwoofer channel, while three selectable output configurations provide design flexibility. Its 100 dB signal-to-noise ratio and dynamic range help preserve low-level detail in compact enclosures where system noise is easier to hear. Output filtering, crossover behavior, gain settings, and protection thresholds must be validated for the selected speaker load.
추천
Automotive Audio Amplification
The STA323W13TR can be evaluated for automotive audio amplification when the vehicle platform requires a compact digital 2.1-channel output stage. Its 10 V to 36 V operating range is relevant to conventional automotive power rails, and the integrated protections support robust operation after the power system and speaker loads are validated. Automotive qualification, environmental temperature range, electromagnetic behavior, and load-dump requirements must be confirmed for the exact ordering code; the product listing does not establish AEC-Q100 qualification. The power layout also needs transient protection beyond the integrated under-voltage and short-circuit functions.
추천
Digital Audio Reference Platform
The STA323W13TR can form the output section of a digital audio reference platform used to compare codecs, processors, and power-stage behavior. Supporting input rates from 32 kHz to 192 kHz makes it useful for repeatable test configurations, while the 100 dB signal-to-noise ratio and dynamic range provide useful headroom for source-quality measurements. Instrument the digital interface and speaker outputs with appropriate test points, and document the selected output configuration because different modes may alter channel routing and loading. Thermal testing should include the highest supported sample-rate and multi-channel operating condition.

설계 노트
Treat the PowerSSO-36 exposed pad as the primary thermal path. Use the manufacturer-recommended pad geometry and thermal-via pattern, retain uninterrupted ground copper where permitted, and avoid placing heat-generating components directly beneath the exposed area. Validate the highest expected multi-channel output condition at the minimum intended supply voltage and maximum ambient temperature; the 40 W rating alone does not establish the allowable dissipation for every output configuration.
Design the supply path for the actual DDX output configuration rather than the nominal 40 W headline value. Check input-voltage tolerance, startup behavior, ripple, current limit, and the voltage required to sustain low distortion into the selected speaker impedance. The device operates from 10 V to 36 V, so a nominal 12 V automotive-style rail has limited headroom at high output power, while a higher rail increases internal switching and thermal stress.
Follow the manufacturer reference layout for the PowerSSO-36 footprint, exposed pad, input and output networks, digital interface, and decoupling. Keep high-current output loops compact and separate from sensitive digital-audio routing. Place local supply capacitors at the power pins with short, low-inductance paths, and verify the board's copper thickness, via arrangement, and thermal performance with the final enclosure and speaker loads.
Do not assume that every family suffix has identical output power, channel routing, protection timing, or configuration limits. The STA323W13 suffix is tied to the 40 W, three-configuration description used on this page, while adjacent family variants require their own electrical tables. Also verify the exposed-pad connection, output-filter components, speaker impedance, digital input format, and gain settings before releasing a replacement into production.
