Compressors  
The STA323W is an integrated solution of digital  
audio processing, digital amplifier control, and  
DDX-Power Output Stage, thereby creating a  
high-power single-chip DDX® solution comprising  
of high-quality, high-efficiency, all digital amplifica-  
tion.  
Automodes™  
– 32 Preset EQ Curves  
– 15 Preset Crossover Settings  
– Auto Volume Controlled Loudness  
– 3 Preset Volume Curves  
– 2 Preset Anti-Clipping Modes  
– Preset Nighttime Listening Mode  
– Preset TV AGC  
The STA323W power section consists of four in-  
dependent half-bridges. These can be configured  
via digital control to operate in different modes. 2.1  
channels can be provided by two half-bridges and  
a single full-bridge, providing up to 2x10W +  
1x20W of power output. 2 Channels can be provid-  
ed by two full-bridges, providing up to 2x20W of  
power. The IC can also be configured as a single  
paralelled full-bridge capable of high-current oper-  
ation and 1x40W output.  
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  
Also provided in the STA323W are a full assort-  
Muting Selectable DDX® Ternary or Binary
