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