  • The STA333IS is an integrated circuit comprising digital audio processing, digital amplifier control and an FFXpower output stage to create a high-power, single-chip FFX solution for all-digital amplification with high quality and high efficiency.

    The STA333IS power section consists of four independent half-bridge stages. Two channels can be provided by two full bridges, delivering up to 10 W + 10 W of power.
    Also featured in the STA333IS are new advanced modes for reducing AM radio interference. The serial audio data input interface accepts all possible formats, including the popular I2S format. Two channels of FFXprocessing are provided.
    The STA333IS 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.

    主要特性

    • Wide-range supply voltage (4.5 V - 20 V)
    • 2 channels of ternary PWM (stereo mode)
    • 2 channels of 24-bit FFX
    • 100 dB SNR and dynamic range
    • Selectable 32- to 192-kHz input sampling rates
    • Digital gain -80 dB to +48 dB in 0.5 dB steps
    • Software volume update
    • Individual channel and master gain/attenuation
    • Individual channel and master software and hardware mute
