STA339BWSTR Sound Terminal from STMicroelectronics

The STA339BWSTR is an advanced sound terminal from STMicroelectronics, designed to deliver a high-quality audio experience for a wide range of consumer electronics. This integrated circuit is part of ST's Sound Terminal® family and offers a fully integrated digital audio processing solution with power amplification capabilities.

At the heart of the STA339BWSTR is a digital audio processor that features a wide range of audio processing technologies. It includes a 24-bit, high-performance audio DSP, and a high-efficiency digital power amplifier. With this combination, the STA339BWSTR is capable of delivering up to 2 x 10 watts of continuous average power to an 8-ohm load with 10% total harmonic distortion plus noise (THD+N), or 2 x 20 watts into a 4-ohm load, ensuring robust and powerful sound output for even the most demanding audio applications.

This sound terminal supports a flexible range of input formats, including I²S and TDM digital audio interfaces, making it easy to integrate into various digital audio systems. It also boasts an advanced PWM (Pulse Width Modulation) output stage with FFXTM (Full Flexible Amplification) technology, which allows for high power efficiency, reduced external component count, and excellent audio performance with low distortion.

The STA339BWSTR comes in a compact 36-pin VFQFPN (very fine pitch quad flat package no lead) package, which is designed to save space on the printed circuit board, making it ideal for space-constrained applications such as flat-screen TVs, wireless speakers, and soundbars.

For developers and manufacturers, the STA339BWSTR offers a high level of integration, simplifying the design process and reducing time to market. It includes built-in features such as a programmable dynamic range compressor, which helps to prevent audio distortion, and an advanced clip detection feature that protects speakers from damage due to excessive power output.

In summary, the STA339BWSTR from STMicroelectronics is a sophisticated audio solution that combines digital audio processing with high-efficiency power amplification. It is designed to meet the needs of modern audio applications, offering superior sound quality, high power efficiency, and ease of integration, all in a compact and cost-effective package.
