TAS3103DBT

The Texas Instruments TAS3103DBT is a fully configurable digital audio processor that utilizes a 48-bit data path and 28-bit filter coefficients for high-fidelity audio preservation. It features a single-cycle 28 x 48-bit multiplier and a 76-bit accumulator, enabling complex audio manipulations.

This processor supports four serial audio input channels and three serial audio output channels, with sample rates ranging from 8 kHz to 96 kHz. It accommodates 15 stereo/TDM data formats and supports independent 16-, 18-, 20-, 24-, and 32-bit word sizes. Control is managed via an I²C interface, allowing for serial master/slave operation.

Key features include programmable digital bass and treble controls, soft volume control, dither, loudness compensation, and VU meter/spectral analysis output. It also offers programmable channel delay up to 42 ms at 48 kHz and a dynamic range of 192 dB. The device operates on a single 3.3-V power supply and is housed in a 38-pin TSSOP package.

The TAS3103DBT is suitable for digital audio interfacing applications, providing a robust platform for audio signal processing with features like 3D effects and reverb, programmable digital mixers, and a 12-band digital parametric EQ.
