Product Overview

The STA309A13TR is a high-performance multi-channel digital audio processor with DDX® (direct digital amplification) technology. It is designed for applications requiring high-quality, high-efficiency digital audio processing and amplification. This single-chip solution supports a wide range of digital audio formats and provides extensive control and processing capabilities.

Key Features

• 8 Channels of 24-bit DDX® Amplification: Supports high-fidelity audio output.
• High SNR and Dynamic Range: Exceeds 100 dB, ensuring clear and detailed audio.
• Selectable Input Sample Rates: Supports rates from 32 kHz to 192 kHz, including DSD/SACD inputs.
• Digital Gain/Attenuation: Adjustable from +58 dB to -100 dB in 0.5-dB steps.
• Individual and Master Gain Control: Includes channel trim from -10 dB to +10 dB.
• Advanced Audio Processing: Features up to 10 independent 32-bit user-programmable biquads (EQ) per channel, bass/treble control, and dynamic range compression.
• Automode™: Offers preset EQ curves, volume control, downmixing, and more.
• Flexible Input and Output Mapping: Supports channel mapping for various configurations.
• Power Management: Features automatic zero-detect and invalid input mute, as well as power correction for lower full-power THD.
• High Internal Processing Sample Rate: 192 kHz with 24-bit to 36-bit precision.
