DESCRIPTION

· The STA333SML is an integrated circuit designed for digital audio processing, digital amplifier control, and FFX power output, providing a high-power, single-chip FFX solution for all-digital amplification with high quality and efficiency.
· It includes four independent half-bridge stages, capable of delivering up to 10 W + 10 W of power through two full bridges.
· Features advanced modes for AM radio interference reduction and supports I²S format for serial audio data input.
· Part of the Sound Terminal® family, it offers cost-effective, low-power dissipation, and sound-enriched digital audio streaming to speakers.

FEATURES

· Wide-range supply voltage (4.5 V - 18 V).
· 2 channels of ternary PWM (stereo mode) and 24-bit FFXTM.
· 100 dB SNR and dynamic range with digital gain up to +24dB.
· Sample rates from 32 to 48 kHz with a fixed MCLK at 256 x fs.
· Automatic zero-detect and invalid input detect mute.
· Short-circuit detection at startup and embedded thermal-overload protection.
· 2-channel I²S input data interface and 2 Hz DC cut filter.
· 96 kHz internal processing sample rate with 24-bit precision.
