STA335W Datasheet PDF - ST Microelectronics

●Description FFX

●The STA335W is an integrated solution of digital audio processing, digital amplifier control, and FFX -power output stage, thereby creating a high-power single-chip FFX solution comprising high-quality, high-efficiency, all digital amplification.

●Features

●■ Wide voltage supply range

●    – 5 V to 26 V (operating range)

●    – 30 V (absolute maximum rating)

●■ 2 channels of ternary PWM (stereo mode) (2 x 20 W into 8Ωat 18 V)

●■ 2.0 channels of 24-bit FFX100 dB SNR and dynamic range

●■ 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

●■ Individual channel and master soft/hard mute

●■ Automatic zero-detect mute

●■ Automatic invalid input-detect mute

●■ 2-channel I2S input data interface

●■ Advanced AM interference frequency switching and noise suppression modes

●■ Selectable high- or low-bandwidth noise-shaping topologies

●■ Variable max power correction for lower full-power THD

●■ Selectable clock input ratio

●■ 96 kHz internal processing sample rate, 24 to 28-bit precision
