Digital Audio Processor - TAS3103
Datasheet Errata

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.
