STA335MLJ13TR

Overview

The STA335MLJ13TR is a Class-D audio amplifier integrated circuit manufactured by STMicroelectronics. It features a 2-channel stereo output configuration housed in a PowerSSO-36 package. The device operates within a supply voltage range of 5V to 26V and delivers an output power of 20W per channel into an 8-ohm load. Key electrical specifications include a total harmonic distortion plus noise (THD+N) of 0.2% and an operating supply current of 52 mA. The component supports an extended operating temperature range from -20°C to +70°C.

Feature Summary

• Integrates digital audio processing with high-efficiency Class-D power amplification on a single die
• Provides automatic gain control functionality for optimized signal handling
• Operates without the need for external microcontroller assistance for basic amplification tasks

Applications

• Audio subsystems requiring compact, high-efficiency amplification
• Stereo audio playback circuits in consumer electronics
• Embedded audio processing applications

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'J13TR' matches the required tape-and-reel packaging format. Check for obsolescence notices as some sources indicate scheduled discontinuation. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the official datasheet before procurement.

Selection Notes

Select this component when a monolithic solution combining digital processing and analog amplification is required. The PowerSSO-36 package offers a balance between thermal performance and board space efficiency. Consider the 5V to 26V supply range for flexibility in system design. Verify that the 0.2% THD+N specification meets the audio quality requirements of the target application compared to higher-fidelity alternatives.

Part Context

This part belongs to the STA33x series of audio amplifiers from STMicroelectronics. It shares architectural similarities with the STA333ML but includes specific interface or feature variations denoted by the suffix. The series is designed for applications demanding high efficiency and reduced external component count by integrating necessary digital logic directly onto the amplifier die.

Replacement Considerations

The STA333ML13TR is a related variant within the same family. Verify pin-to-pin compatibility and functional equivalence regarding digital interfaces and power specifications before substitution. Differences in suffixes may indicate variations in packaging or specific feature sets.
