Digital Audio Processor - TAS3103

TAS3103 (NRND)

Digital Audio Processor


Not Recommended for New Designs (NRND)

Replaced By TMS320C5532– The device has SIMILAR FUNCTIONALITY but is not functionally equivalent to the compared device.

TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.


The TAS3103 is a fully configurable digital audio processor that preserves high-quality audio by using a 48-bit data path, 28-bit filter coefficients, and a single cycle 28 x 48-bit multiplier and 76-bit accumulator. Because of the coefficient-configurable fixed-program architecture of the TAS3103, 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 TAS3103 uses 1.8-V core logic with 3.3-V I/O buffers, and requires only 3.3-V power. The TAS3103 is available in a 38-pin TSSOP package.
