TAS3001CPWG4

Audio Special Purpose Overview

The TAS3001CPWG4 is a fixed-function, 32-bit stereo digital audio processor in a 28-pin TSSOP package. It features a dual-input mixer, six cascaded second-order IIR biquad filters for parametric equalization, and programmable bass/treble controls. The device operates on a single 3.3 V supply with an operating temperature range of 0°C to 70°C. Audio data interfaces support I2S, left-justified, and right-justified formats at sampling rates from 32 kHz to 96 kHz. Configuration is managed via an I2C serial control interface.

Audio Special Purpose Feature Summary

• Stereo digital audio processing with a 32-bit data path and 108-dB dynamic range
• Six-band parametric equalization using high-precision, limit-cycle-free second-order IIR filters
• Programmable two-input digital mixer with independent scaling capabilities
• Soft volume and true soft mute functions with artifact-free transitions

Audio Special Purpose Applications

• Digital audio controls including volume, bass, treble, and parametric equalization
• Loudspeaker and microphone frequency response correction via parametric equalization
• Active crossover implementation for multi-way loudspeaker systems

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'G4' against current Texas Instruments documentation to confirm lead times and availability status. Confirm that the 28-TSSOP package dimensions match the target PCB footprint requirements. Ensure the I2C address configuration pins (CS1, CS2) are correctly set for the system design.

Audio Special Purpose Selection Notes

Select this component for applications requiring high-fidelity digital filtering without external DSP resources. The device supports sample rates up to 96 kHz and requires a master clock input of 256 times the sampling frequency. Verify that the system architecture can accommodate the required I2C control lines and serial audio data connections.

Audio Special Purpose Part Context

The TAS3001 is part of Texas Instruments' DAV-Audio Products line. It serves as a specialized solution for digital audio signal conditioning, replacing analog tone control circuits with programmable digital alternatives. The 'CPW' designation indicates the commercial temperature range and TSSOP package type.

Audio Special Purpose Replacement Considerations

Check for updated revisions or pin-compatible alternatives within the TI audio DSP portfolio if the current part is discontinued. Verify functional equivalence regarding filter coefficient formats and I2C register maps when considering cross-model substitutions.
