TAS3002PFB

Audio Special Purpose Overview

The TAS3002PFB is a system-on-a-chip audio signal processor manufactured by Texas Instruments. It integrates a 32-bit digital audio processor with a 24-bit stereo codec, replacing conventional analog equalization with digital parametric equalization, dynamic range compression, and loudness contour functions. The device supports serial audio interfaces including I2S, left justified, and right justified formats with word lengths of 16, 18, 20, or 24 bits. It operates on a single 3.3-V power supply within an industrial temperature range of 0°C to 70°C.

Audio Special Purpose Feature Summary

• Integrated 24-bit stereo ADC and DAC with two I2C-selectable single-ended inputs per channel
• Programmable seven-band parametric equalization using cascaded biquad filters
• Supports 13 serial interface formats (I2S, Left/Right Justified) for 16-24 bit data
• Includes programmable soft volume, bass/treble control, and dynamic range compression/expansion

Audio Special Purpose Applications

• Digital speakers and active loudspeaker systems
• Automotive audio processing units
• Home theater receivers and amplifiers
• Professional audio mixing consoles

Audio Special Purpose Procurement Notes

Verify the package type matches the 48-TQFP (7x7 mm) specification. Confirm the operating temperature grade corresponds to the commercial range (0°C to 70°C). Ensure the design accommodates the single 3.3 V power supply requirement for both analog and digital sections. Check for availability as this component may be subject to lifecycle changes.

Audio Special Purpose Selection Notes

Select this component when a combined DSP and codec solution is required for parametric equalization and tone control. It is suitable for applications needing I2C programmability for volume, bass, and treble adjustments. Consider the internal PLL requirements for clock generation via external crystal or master clock input. Verify that the available GPI terminals meet the hardware control needs for mute and filter selection.

Audio Special Purpose Part Context

The TAS3002PFB belongs to the TAS3002 series of digital audio processors from Texas Instruments. It is designed to replace discrete analog equalization circuits with flexible digital signal processing capabilities. The PFB suffix indicates the specific tray packaging configuration for the 48-TQFP package variant.

Audio Special Purpose Replacement Considerations

The TAS3004 is a similar digital audio processor with codec functionality from Texas Instruments. Designers should verify pin compatibility and register map differences before substitution.
