TAS5518PAGG4

Audio Special Purpose Overview

The TAS5518PAGG4 is an 8-channel digital audio PWM processor manufactured by Texas Instruments. It integrates a Digital Audio Processor (DAP) with I2C control and serial data interfaces (I2S). The device operates on a 3V to 3.6V supply and supports sampling rates from 32kHz to 192kHz. It features biquad filters, bass/treble controls, volume management, and dynamic range compression. Packaged in a 64-TQFP (10x10 mm) case, it functions as a modulator for digital audio interfacing applications.

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'G4' against the official Texas Instruments datasheet SLES115 to confirm package type and environmental compliance details. Ensure the 64-TQFP physical dimensions match the design requirements. Confirm that the 3V–3.6V supply voltage range aligns with the target system power architecture.

Audio Special Purpose Selection Notes

Select this component when an 8-channel digital audio processing solution with integrated PWM modulation is required. It is suitable for designs needing flexible input mixing, EQ, and DRC capabilities controlled via I2C. Verify compatibility with the host processor's I2S interface timing and the available I2C bus address space.

Audio Special Purpose Part Context

The TAS5518 series serves as a comprehensive digital audio front-end processor. The TAS5518PAGG4 variant specifically denotes the 64-TQFP package configuration. It is part of Texas Instruments' portfolio for high-performance digital speaker systems, often paired with external power amplifiers to create complete audio solutions.

Audio Special Purpose Replacement Considerations

Check for TAS5518CPAG or TAS5518PAG variants within the same family. Verify pinout and register compatibility before substitution. Ensure the replacement part meets the same 64-TQFP package and electrical specifications.
