February 2014 DocID13365 Rev 3 1/50 STA333W 2 channel high-efficiency digital audio system Sound Terminal™ Datasheet - production data Features Wide supply-voltage range (4.5 V - 20 V) 2 power output configurations – 2 channels of binary PWM (stereo mode) – 2 channels of ternary PWM (stereo mode) PowerSSO-36 with exposed pad down 2 channels of 24-bit DDX® 100-dB SNR and dynamic range Selectable 32- to 192-kHz input sample rates I²C control with selectable device address Digital gain -80 dB to +48 dB in 0.5-dB steps Software volume update Individual channel and master gain/attenuation Individual channel and master software and hardware mute Independent channel volume bypass Automatic zero-detect mute Automatic invalid input detect mute 2-channel I²S input data Interface Selectable clock input ratio Input channel mapping Automatic volume control for limiting maximum power 96-kHz internal processing sample rate, 24-bit precision Advanced AM interference frequency switching and noise suppression modes Thermal-overload and short-circuit protection embedded Video application: 576 * f S input mode support Applications LCD DVD Cradle Digital speaker Wireless-speaker cradle Description The STA333W is an integrated circuit comprising digital audio processing, digital amplifier control and DDX® power output stage to create a high- power, single-chip DDX® solution for all-digital amplification with high quality and high efficiency. The STA333W power section consists of four independent half-bridges stages. These can be configured via digital control to operate in different modes. 2 channels can be provided by two full bridges, providing up to 20 W + 20 W of power. Also provided in the STA333W are new advanced AM radio interference reduction modes. The serial audio data input interface accepts all possible formats, including the popular I²S format. Three channels of DDX® processing are provided. The STA333W is part of the Sound Terminal™ family that provides full digital audio streaming to the speaker offering cost effectiveness, low power dissipation and sound enrichment.
