TAS5508APAG

Audio Special Purpose Overview

The TAS5508APAG is an eight-channel digital audio PWM processor manufactured by Texas Instruments. It integrates a Digital Audio Processor (DAP) with I2C and I2S interfaces for system control and data input. The device operates on a 3V to 3.6V supply within a 0°C to 70°C temperature range. It supports sampling rates from 32kHz to 192kHz and features an internal PLL, input crossbar mixer, biquad filters, dynamic range compression, and loudness compensation. The component is housed in a 64-TQFP package.

Audio Special Purpose Feature Summary

• Eight-channel digital audio processing with integrated PWM modulation
• Comprehensive DAP architecture including biquad filters, bass/treble controls, and dynamic range compression
• I2C serial control interface and I2S/LJ/RJ serial audio ports
• Built-in loudness compensation and automatic AM interference avoidance

Audio Special Purpose Applications

• Digital audio interfacing systems
• DVD receivers
• Multichannel speaker systems using open-loop digital Class-D amplifiers

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'A' against official documentation, as standard listings often reference variants like TAS5508BPAG or TAS5508CPAG. Confirm current availability status directly with the manufacturer or authorized distributors, as older series components may have limited stock or end-of-life implications.

Audio Special Purpose Selection Notes

Select this component for designs requiring high channel count integration without external DSPs. Ensure the host system provides compatible I2S or Left/Right Justified audio formats. Verify that the power supply voltage remains strictly between 3V and 3.6V to maintain recommended operating conditions.

Audio Special Purpose Part Context

This part belongs to the TAS5508 family of digital audio PWM processors. It is designed to drive digital Class-D amplifiers such as the TAS5121. The 'A' suffix typically denotes a specific manufacturing revision or qualification level within the Texas Instruments product line.

Audio Special Purpose Replacement Considerations

TAS5508BPAG and TAS5508CPAG are documented variants within the same family. Verify pin compatibility and feature parity before substitution.
