  • The STA311B is a single-chip solution for digital audio processing and control in multichannel applications and provides output capabilities for FFX™ (full flexible amplification). In conjunction with an FFX™ power device, it provides high-quality, high-efficiency, all digital amplification. The device is extremely versatile, allowing for input of most digital formats including 6.1/7.1-channel and 192 kHz, 24-bit DVD-audio, DSD/SACD. In the 5.1 application the additional 2 channels can be used for audio line-out or headphone drive.

    Key Features

    • 8 channels of 24-bit FFX
    • >100 dB SNR and dynamic range
    • Selectable 32 kHz-192 kHz input sampling rates
    • 6 channels of DSD/SACD
    • Digital gain/attenuation +58 dB to -100 dB in 0.5 dB steps
    • Advanced “pop-free” operation
    • Digital “pop-free” operation for single-ended mode
    • Soft volume update
    • Individual channel and master gain/attenuation plus channel trim (-10 dB to +10 dB)
    • Up to 10 independent 32-bit user-programmable biquads (EQ) per channel
    • Bass/treble tone control
    • Pre- and post-EQ full 8-channel input mix on all 8 channels
    • Dual independent limiters/compressors
    • Dynamic range compression or anti-clipping modes
