2 DESCRIPTION

Compressors

The STA328 is an integrated solution of digital au-

dio processing, digital amplifier control, and DDX-

Power Output Stage, thereby creating a high-pow-

er single-chip DDX® solution comprising of high-

quality, high-efficiency, all digital amplification.

■ 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 STA328 power section consists of four inde-

pendent 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 2x40W +

1x80W of power output. 2 Channels can be provid-

ed by two full-bridges, providing up to 2x80W of

power. The IC can also be configured as a single

paralelled full-bridge capable of high-current oper-

ation and 1x160W output.

■ Input and Output Channel Mapping

■ AM Noise Reduction and PWM Frequency

Shifting Modes

■ Soft Volume Update and Muting

Also provided in the STA328 are a full assortment

of digital processing features. This includes up to

4 programmable 28-bit biquads (EQ) per channel,

■ Auto Zero Detect and Invalid Input Detect

Muting Selectable DDX® Ternary or Binary
