TAS3001CPWR

Audio Special Purpose Overview

The Texas Instruments TAS3001CPWR is a fixed-function, 32-bit digital audio signal processor housed in a 28-pin TSSOP package. It operates on a single 3.3 V supply within a temperature range of 0°C to 70°C. The device features two stereo serial audio inputs and one output, supporting sample rates from 32 kHz to 96 kHz with word lengths of 16, 18, or 20 bits. Key processing capabilities include a programmable two-input mixer, six cascaded second-order IIR biquad filters for parametric equalization, and independent bass and treble shelf controls. All parameters are configured via an I²C interface.

Audio Special Purpose Feature Summary

• Stereo Digital Audio Processing: Supports nine serial data formats (I2S, left/right justified) and provides a 108-dB dynamic range.
• Parametric Equalization: Contains six cascaded, limit-cycle-free second-order IIR filters per channel using 24-bit coefficients.
• Tone and Volume Control: Features programmable digital bass/treble shelves (-18 dB to +18 dB) and soft volume/mute functions.
• Dual Input Mixing: Includes a programmable stereo mixer allowing independent scaling of two digital audio inputs.

Audio Special Purpose Applications

• Digital audio system control for volume, bass, treble, and parametric equalization.
• Loudspeaker active crossovers for multi-way speaker systems.
• Frequency response correction for loudspeakers and microphones.

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'PWR' corresponds to the Tape & Reel packaging format as indicated in local product fields. Confirm that the 'TA' designation aligns with the standard commercial temperature range (0°C to 70°C) specified in the datasheet's ordering information table. Ensure the I²C address pins (CS1/CS2) are configured correctly for the target system bus topology.

Audio Special Purpose Selection Notes

Select this component when a fixed-function digital solution is required for stereo audio processing without the complexity of a general-purpose DSP. It is suitable for applications needing precise parametric EQ and tone control with a 32-bit internal data path. Verify that the external master clock (MCLK) can provide the necessary 256x sampling frequency reference for the internal PLL.

Audio Special Purpose Part Context

The TAS3001 is part of Texas Instruments' DAV-Audio Products line, specifically designed for high-fidelity digital audio processing. It serves as a specialized alternative to discrete analog tone controls or complex programmable DSPs, offering a dedicated architecture for mixing, filtering, and volume management in consumer audio equipment.

Audio Special Purpose Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should evaluate other TI audio processors or generic DSPs based on pin compatibility and software register mapping if replacement is necessary.
