This document describes the features and characteristics of a 2.1-channel high-efficiency digital audio system, including wide voltage supply range, multiple power output configurations, 24-bit FFX® and 100 dB SNR, etc.
The STA339BW is a 2.1-channel high-efficiency digital audio system designed for applications requiring high-quality audio processing and power output. It features a wide voltage supply range from 5V to 26V and supports three power output configurations, including stereo mode and 2.1 mode with independent channel volume and DSP bypass.
The device includes advanced digital signal processing features such as a 24-bit FEX with 100 dB SNR, selectable input sample rates up to 192 kHz, and 28-bit resolution. It offers various audio effects including bass/treble tones, de-emphasis control, and dynamic range compression. The STA339BW is fully compatible with the STA339BWS and includes thermal overload and short-circuit protection.
