STA333W13TR

Audio Special Purpose Overview

The STA333W13TR is a fully integrated digital audio system from STMicroelectronics, designed for high-efficiency amplification. It combines digital audio processing, control logic, and a DDX power output stage into a single chip. The device supports a supply voltage range of 4.5 V to 20 V and operates within an ambient temperature range of 0°C to 70°C. It features two channels of 24-bit DDX modulation with a 100-dB signal-to-noise ratio. The component utilizes I²S for data input and I²C for configuration, housed in a PowerSSO-36 package with an exposed pad down (EPD) for thermal management.

Audio Special Purpose Feature Summary

• Integrated digital audio processing and DDX power output stage for single-chip solution
• 2-channel 24-bit DDX modulation with 100-dB SNR and dynamic range
• I²S interface for serial audio data and I²C interface for device control
• PowerSSO-36 EPD package with wide supply voltage support (4.5 V - 20 V)

Audio Special Purpose Applications

• Pre-amplifier circuits
• Digital speakers
• Audio terminals

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix '13' against the manufacturer's official datasheet to confirm pinout and functional variations. Ensure the PowerSSO-36 EPD footprint matches the PCB layout requirements. Confirm that the industrial grade and operating temperature range meet the target application specifications before finalizing procurement.

Audio Special Purpose Selection Notes

Select this component when a fully integrated digital amplifier with embedded DSP capabilities is required. It is suitable for applications needing direct digital input via I²S without external microcontrollers for basic operation. Consider the 4.5 V to 20 V supply range and the 2-channel stereo configuration. Verify compatibility with the desired I²C address and sample rate settings during the design phase.

Audio Special Purpose Part Context

The STA333W13TR belongs to the Sound Terminal family of digital audio systems. This series focuses on providing cost-effective, high-efficiency solutions by integrating processing and power stages. The 'STA333W' designation indicates a specific variant within this family, distinguished by its channel count and modulation type compared to other models like the STA333ML or STA339.

Audio Special Purpose Replacement Considerations

Check for exact pin-compatible alternatives within the STA333W series. Verify if variants with different supply voltage ranges or additional DSP features are available. Ensure any substitute maintains the same PowerSSO-36 EPD package dimensions and thermal characteristics.
