STA369BWSTR

Audio Special Purpose Overview

The STA369BWSTR is a fully integrated digital audio subsystem from STMicroelectronics, belonging to the Sound Terminal family. It combines digital audio processing, amplifier control, and power output stages into a single chip using Full Flexible Amplification (FFX) technology. The device supports 2-channel stereo operation with I2S interface and I2C control. It operates on a supply voltage range of 4.5 V to 21.5 V and functions within an ambient temperature range of -20°C to +70°C. Housed in a 36-pin PowerSSO-36 EPD package, it is designed for surface mount installation.

Audio Special Purpose Feature Summary

• Integrates digital audio processing, amplifier control, and FFX power output stage
• Supports I2S serial audio input and I2C configuration interface
• Operates on supply voltages between 4.5 V and 21.5 V
• Available in 36-PowerBFSOP (PowerSSO-36 EPD) surface-mount package

Audio Special Purpose Applications

• Pre-amplifier circuits
• Space-constrained audio applications
• Flat-screen TVs
• MP3 docking stations

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'W' against official STMicroelectronics documentation to confirm packaging details such as reel size or tape specifications. Ensure the component grade and moisture sensitivity level requirements align with the target assembly process. Confirm that the PowerSSO-36 EPD package thermal characteristics meet the design's heat dissipation needs.

Audio Special Purpose Selection Notes

Select this component when a fully digital audio stream from source to speaker is required to minimize external components. The STA369BWSTR is suitable for designs needing integrated DSP capabilities and high-efficiency amplification without external multiplexers or ADCs. Verify that the 2-channel stereo configuration meets the system's channel count requirements.

Audio Special Purpose Part Context

This part belongs to the STA369BWS series within the Sound Terminal family. The 'W' suffix typically indicates a specific packaging variant, such as Tape and Reel, while the base model STA369BWS represents the core integrated processor functionality. Other variants in the family may offer different pinouts or power configurations.

Audio Special Purpose Replacement Considerations

Direct substitutes within the same family include the STA369BW and STA369BWS. Verify pin compatibility and software configuration settings when replacing the WSTR variant with other package types like cut tape or tube versions.
