STA328 Evaluation board

The STA328 is a single chip solution for digital audio processing and control in stereo applications. It provides high-quality, high-efficiency, all digital amplification. The internal 24bit digital signal processing allows for high resolution processing at all standard input sample frequencies. Processing includes volume control, filtering, bass management and gain compression/limiting. Filtering includes ten user-programmable 28bit biquads for EQ per channel, as well as bass, treble and DC blocking. External clocking can be provided at four different ratios of the input sample frequency. All sample frequencies are upsampled for processing. Each internal processing channel can receive any input channel, allowing flexibility and the ability to perform active digital crossover for powered loudspeaker systems. The serial audio data interface accepts many different formats, including the popular I?S format.
