Overview
The TAS3204PAGR, produced by Texas Instruments, is a highly-integrated audio system-on-chip (SOC) designed for advanced digital audio processing. This device combines a fully-programmable 48-bit digital audio processor with comprehensive analog audio interfaces, making it suitable for a wide range of audio applications. The TAS3204 is programmable using the PurePath Studio™ software development environment, which is a graphical, drag-and-drop tool that simplifies software development while leveraging the full capabilities of the audio DSP core.
The TAS3204 features a custom-designed 135-MHz digital audio processor with a 76-bit accumulator, ensuring high precision during arithmetic operations. It includes four differential 102 dB DNR ADCs and four differential 105 dB DNR DACs, providing high-quality audio and robustness against noise sources.
