1 Introduction

The TAS3103A is a fully configurable digital audio processor that preserves high-quality audio by using a 48-bit data

path, 28-bit filter coefficients, a single-cycle 28

× 48-bit multiplier and a 76-bit accumulator. Because of the

coefficient-configurable fixed-program architecture of the TAS3103A, a complete set of user-specific audio

processing functions can be realized, with short development times, in a small, low-power, low-cost device. A

personal computer (PC) GUI-based software development package and a comprehensive evaluation board provide

additional facilities to further reduce development times. The TAS3103A uses 1.8-V core logic with 3.3-V I/O buffers,

and requires only 3.3-V power. The TAS3103A is available in a 38-pin TSSOP package.
