TAS5504PAGR

Audio Special Purpose Overview

The TAS5504PAGR is a 4-channel digital audio PWM processor manufactured by Texas Instruments. It integrates a Digital Audio Processor (DAP) with I2C and I2S interfaces for serial data input. The device operates on a 3V to 3.6V supply voltage within a commercial temperature range of 0°C to 70°C. It supports sampling rates from 32kHz to 192kHz and features internal PLL clock generation. Packaged in a 64-TQFP (10x10mm) case, the 'R' suffix indicates Tape & Reel packaging.

Audio Special Purpose Feature Summary

• Integrated 4-channel Digital Audio Processor (DAP) with input crossbar mixer
• Supports I2S, Left Justified, and Right Justified serial audio formats
• Includes programmable biquad filters, bass/treble controls, and dynamic range compression
• Features automatic AM interference avoidance and power supply volume control

Audio Special Purpose Applications

• Digital audio interfacing systems
• Speaker processing circuits
• Home theater audio processors

Audio Special Purpose Procurement Notes

Verify the package type matches the 64-TQFP specification. Confirm the operating temperature range meets the 0°C to 70°C requirement. Ensure the supply voltage aligns with the 3V to 3.6V limits. Check that the serial interface configuration supports the required sample rates up to 192kHz.

Audio Special Purpose Selection Notes

Select this component for designs requiring four independent audio channels with digital processing capabilities. The integrated DAP reduces external component count compared to discrete solutions. Verify compatibility with the host controller's I2C address and serial data timing requirements before integration.

Audio Special Purpose Part Context

This part belongs to the TAS5504 series of digital audio PWM processors. It is designed to replace analog audio processing stages in digital speaker systems. The PAGR variant specifically denotes the surface-mount TQFP package with tape-and-reel delivery format.
