Product overview

描述

The STA350Bx 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, and all-digital amplification. The STA350Bx is based on an FFX (fully flexible amplification) processor, a proprietary technology from STMicroelectronics. FFX is the evolution and the enlargement of ST’s ternary technology: the new processor can be configured to work in ternary, binary, binary differential and phase-shift PWM modulation schemes.
The STA350Bx contains the ternary, binary and binary differential implementations, a subset of the full capability of the FFX processor.
The STA350Bx 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 STA350Bx 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 18 W + 1 x 40 W of music output power, by using standard 4 and 8 Ω speakers. Two channels can be provided by two full-bridges, providing up to 2 x 50 W of music power, by using standard 6 Ω speaker or 2 x 40 W by using 8 Ω speakers at 25 V. The IC can also be configured as 2.1 channels with 2 x 40 W provided by the device and external power for FFX power drive. If configured as mono-BTL, the latter is capable of providing up to 1 x 90 W on a standard 3 Ω load or 1 x 75 W by using a 4 Ω, setting the supply voltage at 25 V. Please refer to the package thermal characteristics and application suggestions for more details.
Also provided in the STA350Bx are a full assortment of digital processing features. This includes up to 8 programmable biquads (EQ) per channel. Special digital signal processing techniques are available in order to manage low-frequency quantization noise in case of very low frequency cutoff filter thresholds. The coefficient range -4..4 allows the easy implementation of high shelf filters. Available presets allow the advantage of earlier time-to-market 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 output power level. This feature independently processes the two bands, controlling dynamically the output power level in each band and so providing better sound clarity.
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.
