TAS3002PFBRG4

Audio Special Purpose Overview

The TAS3002PFBRG4 is a system-on-a-chip audio signal processor manufactured by Texas Instruments, housed in a 48-TQFP (7x7 mm) surface-mount package. It integrates a 32-bit digital audio processor with a 24-bit stereo codec, supporting sampling rates of 32 kHz, 44.1 kHz, and 48 kHz. The device operates on a single 3.3 V supply within an operating temperature range of 0°C to 70°C. Key capabilities include programmable seven-band parametric equalization, dynamic range compression, loudness contouring, and soft digital volume control via I2C interfaces.

Audio Special Purpose Feature Summary

• Integrated 24-bit stereo ADC and DAC with two selectable single-ended analog inputs per channel
• Programmable seven-band parametric equalization using cascaded biquad filters
• Supports 13 serial interface formats including I2S, left-justified, and right-justified
• Features dynamic range compression/expansion and programmable loudness contour algorithms

Audio Special Purpose Applications

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

Audio Special Purpose Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's current documentation to confirm RoHS compliance and lead-free status. Ensure the 48-TQFP package dimensions match the target PCB footprint. Confirm that the 0°C to 70°C commercial grade temperature rating meets the environmental requirements of the intended application.

Audio Special Purpose Selection Notes

Select this component when a combined DSP and codec solution is required for digital audio processing. It is suitable for designs needing flexible serial audio interface compatibility and onboard analog input/output. Consider the I2C control overhead and the need for an external microcontroller or EEPROM for parameter storage.

Audio Special Purpose Part Context

This part belongs to the TAS3002 family of digital audio processors from Texas Instruments. It serves as a complete solution for replacing conventional analog equalization circuits with digital parametric filtering. The device simplifies system design by integrating control logic, audio processing, and conversion functions into a single chip.
