2 DESCRIPTION

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
