PowerSSO36 slug (or exposed pad) down  
! Power SSO-36 slug down package  
Applications  
! LCD  
®
! 2 channels of 24-bit DDX  
! 100 dB SNR and dynamic range  
! DVD  
! Selectable 32 kHz to 192 kHz input sample  
! Cradle  
rates  
2
! Digital speaker  
! Wireless speaker cradle  
! I C control with selectable device address  
! Digital gain/attenuation +48 dB to -80 dB steps  
! Software volume update  
Description  
! Individual channel and master gain/attenuation  
The STA333W is an integrated solution of digital  
audio processing, digital amplifier control, and  
! Individual channel and master software and  
hardware mute  
®
DDX -power output stage, thereby creating a  
! Independent channel volume bypass  
! Automatic zero-detect mute  
®
high-power single-chip DDX solution comprising  
of high-quality, high-efficiency, all digital  
amplification.  
! Automatic invalid input detect mute  
2
! 2-channel I S input data Interface  
The STA333W power section consists of four  
independent half-bridges. These can be  
configured via digital control to operate in different  
modes. 2 channels can be provided by two  
full-bridges, providing up to 2 x 20 W of power.  
! Selectable clock input ratio  
! Input channel mapping  
! Variable max power correction for lower  
fullpower  
Also provided in the STA333W are new advanced  
AM radio interference reduction modes. The serial  
audio data input interface accepts all possible  
! 96 kHz internal processing sample rate, 24-bit  
precision  
2
formats, including the popular I S format.  
! Advanced AM interference frequency  
switching and noise suppression modes  
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.  
! Thermal overload and short-circuit protection  
embedded  
! Video application: 576 x fs input mode support
