Description
The STA335BW 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 amplification.
The STA335BW power section consists of four independent 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 2 x 14 W + 1 x 30 W of power
output. Two channels can be provided by two full-bridges, providing up to 2 x 30 W of power.
The IC can also be configured as a 2.1 channels with 2 x 30 W provided by the device and
external power for DDX® power drive. Also provided in the STA335BW are a full assortment
of digital processing features. This includes up to four programmable 28-bit biquads (EQ)
per channel, and bass/treble tone control. Automodes™ enable a time-to-market advantage
by substantially reducing the amount of software development needed for certain functions.
This includes Auto Volume loudness, preset volume curves and preset EQ settings. New
advanced AM radio interference reduction modes. The serial audio data input interface
accepts all possible formats, including the popular I2S format. Three channels of DDX®
processing are provided. This high quality conversion from PCM audio to DDX’s patented
tri-state PWM switching waveform provides over 100 dB SNR and dynamic range.
