TAS5504PAG

Audio Special Purpose Overview

The TAS5504PAG is a four-channel digital audio PWM processor manufactured by Texas Instruments. It integrates a Digital Audio Processor (DAP) with I2C control, supporting sampling rates from 32 kHz to 192 kHz. The device operates on a 3 V to 3.6 V supply and features an internal PLL for clock generation. Key processing capabilities include input crossbar mixing, biquad filters, bass/treble controls, loudness compensation, and dynamic range compression. It utilizes a 64-TQFP package (10x10 mm) and supports I2S and I2C interfaces.

Audio Special Purpose Feature Summary

• Four-channel digital audio processing with integrated PWM modulation
• Supports sampling rates from 32 kHz up to 192 kHz
• Includes biquad filters, bass/treble controls, and loudness compensation
• I2C serial control interface with slave address 0x36

Audio Special Purpose Applications

• Digital audio interfacing systems
• Multi-channel speaker processors
• Home theater audio receivers

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and temperature grade. Confirm that the 64-TQFP variant matches the required PCB footprint dimensions of 10x10 mm. Ensure the power supply voltage remains within the 3 V to 3.6 V operating range during system design.

Audio Special Purpose Selection Notes

Select this component when a four-channel solution with high-resolution audio support up to 192 kHz is required. The integrated DAP reduces external component count by handling filtering and mixing internally. Verify compatibility with the host controller's I2C bus speed and the available master clock frequencies for the internal PLL.

Audio Special Purpose Part Context

This part belongs to the TAS5504 series of digital audio PWM processors. It serves as a complete solution for managing multi-channel audio signals before amplification. The 'PAG' suffix indicates the plastic TQFP package variant designed for surface-mount assembly.
