ST STA333BW handbook
Update: 30 September, 2023
This manual introduces STA333BW, a 2.1-channel 40-watt high-efficiency digital audio system. It has a wide supply voltage range, it can work between 4.5V and 21.5V. It has three power output configurations: 2 channels of ternary PWM (2 x 20W into 8 Ω at 18V) + PWM output; 2 channels of ternary PWM (2 x 20W into 8 Ω at 18V) + ternary stereo line-out; 2.1 channels of binary PWM (left, right, LFE) (2 x 9W into 4 Ω +1 x 20W into 8 Ω at 18V), and features 100-dB SNR and dynamic range FFX, scalable FFX modulation index, selectable 32- to 192-kHz input sample rates, I2C control with selectable device address, digital gain/attenuation +48 dB to -80 dB with 0.5-dB/step resolution, soft volume update with programmable ratio, individual channel and master gain/attenuation, dynamic range compression (DRC) or anticlipping mode, 15 preset crossover filters, 5 preset anticlipping modes, preset night-time listening mode, individual channel soft/hard mute, independent channel volume and DSP bypass, I2S input data interface, input and output channel mapping, automatic invalid input-detect mute, up to 5 user-programmable biquads/channel, three coefficients banks for EQ presets storing with fast recall via I2C interface, bass/treble tones and de-emphasis control, selectable high-pass filter for DC blocking, advanced AM interference frequency switching and noise suppression modes, sub channel mix into left and right channels, selectable high- or low-pass filter.
