ST STA369BWS 2.1-channel 40-watt high-efficiency digital audio system Sound Terminal handbook
The STA369BWS is a 2.1-channel 40-watt high-efficiency digital audio system designed for automotive applications. It features wide-range supply voltage support (4.5 V to 21.5 V) and offers three power output configurations, including ternary PWM and binary PWM modes.
The device includes advanced audio processing capabilities such as FFX with 100-dB SNR, selectable input sample rates up to 192-kHz, and digital gain/attenuation ranging from +48 dB to -80 dB. It supports various dynamic range control (DRC) modes, including dual-band anti-clipper and independent limiters/compressors, along with EQ presets and dedicated LFE processing.
