TAS3001CPWRG4

Audio Special Purpose Overview

The TAS3001CPWRG4 is a fixed-function, 32-bit stereo digital audio processor manufactured by Texas Instruments. It features a dual-input mixer, six cascaded second-order IIR biquad filters for parametric equalization, and programmable bass and treble controls. The device operates on a single 3.3-V supply within an operating temperature range of 0°C to 70°C. It supports serial data formats including I2S, left-justified, and right-justified with sampling frequencies from 32 kHz to 96 kHz. Configuration is managed via an I2C interface.

Audio Special Purpose Feature Summary

• Stereo Digital Audio Processing: Includes a programmable two-input mixer, six-band parametric EQ, and soft volume/mute functions.
• High-Precision Filtering: Utilizes a 32-bit data path with 24 × 32-bit multiplies and limit-cycle-free second-order IIR filter structures.
• Flexible Interfaces: Supports I2S, left-justified, and right-justified serial audio formats alongside an I2C control port.
• Physical Package: Delivered in a 28-pin TSSOP (PW) package suitable for surface mount applications.

Audio Special Purpose Applications

• Digital Audio Controls
• Loudspeaker Active Crossovers
• Measurement-Based Speaker Correction

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'G4' against current manufacturer documentation to confirm compliance status and packaging details. Confirm that the Tape & Reel (TR) packaging matches the required manufacturing line specifications. Ensure the 28-TSSOP footprint aligns with the target PCB design constraints.

Audio Special Purpose Selection Notes

Select this component when a fixed-function digital signal processor is required for stereo audio paths. The device is suitable for systems needing parametric equalization and active crossovers without the complexity of a general-purpose DSP. Verify that the system clock requirements (MCLK at 256x fs) are compatible with the host microcontroller or codec.

Audio Special Purpose Part Context

This part belongs to the TAS3001 series of audio signal processors. The 'CPW' designation indicates the commercial temperature grade and TSSOP package type, while 'G4' typically denotes lead-free and RoHS-compliant manufacturing variations within the Texas Instruments portfolio.

Audio Special Purpose Replacement Considerations

Consult official Texas Instruments documentation for verified cross-reference part numbers. Do not substitute with generic audio processors unless functional equivalence regarding the I2C register map and serial audio timing is confirmed.
