The TAS3001 provides a zero-input limit-cycle-free second-order IIR filtering structure that implements a direct form

I filter structure. This architecture preserves high-quality audio by using a 32-bit data path, 24

× 32-bit multiplies, and

56 bits of precision for some internal calculations. By using 24-bit filter coefficients, the TAS3001 can implement

practically any second-order IIR filter with outstanding fidelity.

Texas Instruments has several tools that provide a powerful and flexible means to develop applications using the

TAS3001. Chapter 8 provides examples of how the TAS3001 can be used to meet various system needs.
