Description
1.1
Overview
The STA328 comprises digital audio processing, digital amplifier control and DDX® power
output stage to create a high-power single-chip DDX® solution for high-quality,
high-efficiency, all digital amplification.
The STA328 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 to give up to 2 x 40 W plus 1 x 80 W of power
output. Two channels can be provided by two full-bridges to give up to 2 x 80 W of power.
The IC can also be configured as a single parallel full-bridge capable of high-current
operation and 1 x 160 W output.
Also provided in the STA328 is 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, 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 patented DDX® 3-state PWM switching provides over 100 dB of SNR and dynamic
range.
