Introducing the STA339BWTR Sound Terminal®

The STA339BWTR from STMicroelectronics is a cutting-edge audio solution that combines the power and fidelity of traditional audio amplifiers with the efficiency and compactness of digital amplifiers. This integrated circuit is part of ST's Sound Terminal® family and is designed to deliver high-quality sound with minimal power consumption, making it an ideal choice for a wide range of audio applications.

The STA339BWTR boasts a 2.1-channel high-efficiency digital audio output, which includes a stereo filter-less class D amplifier and an additional mono full-bridge output for a subwoofer, providing a comprehensive audio amplification solution. This allows designers to create a full-range audio system without the need for external filters or complex circuitry.

One of the key features of the STA339BWTR is its wide supply voltage range, from 4.5V to 18V, which enables it to be used in various applications, from portable devices to home audio systems. The chip also incorporates an advanced PWM (Pulse Width Modulation) processor with an FFX (Full Flexible Amplification) technology, which ensures high-quality audio reproduction with low THD (Total Harmonic Distortion) and noise levels.

The STA339BWTR is equipped with multiple built-in features that enhance its performance and usability. It includes an I²C bus control interface, allowing for easy integration into modern digital systems, and a range of diagnostic functions that help protect the IC from damage due to faults such as short circuits or overheating. Additionally, the chip offers a selectable 32-step volume control, three band tone control, and dynamic range compression, which are all programmable via the I²C interface.

Encased in a 36-pin PowerSSO package with exposed pad up (EP), the STA339BWTR is designed to facilitate efficient heat dissipation, ensuring reliable operation even under high power conditions. This makes the STA339BWTR a versatile and robust audio solution that can deliver exceptional sound quality in a compact form factor.

Whether you are developing a high-performance home theater system, a compact digital speaker, or any other audio product, the STA339BWTR from STMicroelectronics provides the perfect blend of power, efficiency, and audio fidelity to bring your sound to life.
