Product Description

The STA339BW is an integrated solution of digital audio processing, digital amplifier control, and FFX-power output stage, thereby creating a high-power single-chip FFX®solution comprising high-quality, high-efficiency, all digital amplification.
STA339BW is based on FFX (fully flexible amplification) processor, an STMicroelectronics proprietary technology. FFX is the evolution and the enlargement of the ST ternary technology: the new processor can be configured to work in ternary, binary, binary differential and phase shift PWM modulation schemes.
STA339BW contains the ternary, binary and binary differential implementations, a subset of the full capability of the FFX processor.
The STA339BW is part of the Sound Terminal®family that provides full digital audio streaming to the speaker, offering cost effectiveness, low power dissipation and sound enrichment.
The STA339BW power section consists of four independent half bridges. These can be configured via digital control to operate in different modes. 2.1 channels can be provided by two half bridges and a single full bridge, providing up to 2 x 9 W + 1 x 20 W of power output. Two channels can be provided by two full bridges, providing up to 2 x 20 W of power. The IC can also be configured as 2.1 channels with 2 x 20 W provided by the device and external power for FFX power drive.
Also provided in the STA339BW are a full assortment of digital processing features. This includes up to 8 programmable 28-bit biquads (EQ) per channel and bass/treble tone control. Available presets enable a time-to-market advantage by substantially reducing the amount of software development needed for certain functions. This includes audio preset volume loudness, preset volume curves and preset EQ settings. There are also new advanced AM radio interference reduction modes. Dual-band DRC dynamically equalizes the system to provide speaker linear frequency response regardless of the output power level. This feature independently processes the two bands, controlling dynamically the output power level in each band and so providing better sound quality.
The serial audio data input interface accepts all possible formats, including the popular I2S format. Three channels of FFX processing are provided. This high-quality conversion from PCM audio to FFX PWM switching waveform provides over 100 dB SNR and dynamic range.
