STA323W Datasheet

STA323W is a high-efficiency digital audio system produced by STMicroelectronics. It has a wide supply voltage range (10V-36V), three power output configurations (2 x 10 W + 1 x 20 W, 2 x 20 W, 1 x 40 W), thermal protection, under-voltage protection, short-circuit protection, and PowerSO-36 slug down package. In addition, the system also supports 2.1 channels of 24-bit DDX®, 100dB SNR and dynamic range, 32kHz to 192kHz input sample rates, digital gain/attenuation (+48 dB to -80 dB in 0.5dB steps), four 28-bit user programmable biquads (EQ) per channel, I2C control, 2-channel I2S input data interface, individual channel and master gain/attenuation, individual channel and master soft and hard mute, individual channel volume and EQ bypass, DDX® POP free operation, bass/treble tone control, dual independent programmable limiters/compressors, AutoModes™ settings (32 preset EQ curves, 15 preset crossover settings, Auto volume controlled loudness, 3 preset volume curves, 2 preset anti-clipping modes, Preset night-time listening mode, Preset TV AGC), input and output channel mapping, AM noise-reduction and PWM frequency shifting modes, soft volume update and muting, auto zero detect and invalid input detect muting, selectable DDX® ternary or binary PWM output plus variable PWM speeds, selectable de-emphasis, Post-EQ user programmable mix with default 2.1 bass-management settings, variable max power correction for lower full-power THD, four output routing configurations, and selectable switching.
