TAS5508BPAGG4

Audio Special Purpose Overview

The Texas Instruments TAS5508BPAGG4 is an 8-channel digital audio PWM processor designed for high-performance multi-channel audio systems. It operates on a single 3V to 3.6V supply and supports sampling rates from 32kHz to 192kHz. The device integrates a comprehensive Digital Audio Processor (DAP) featuring input crossbar mixing, biquad filters, bass/treble controls, loudness compensation, and dynamic range control (DRC). Communication is handled via I2C serial control and I2S serial data interfaces. Housed in a 64-TQFP package, it functions within a temperature range of 0°C to 70°C.

Audio Special Purpose Feature Summary

• Integrates 8-channel digital audio processing with I2C control and I2S data interface
• Supports sampling rates from 32kHz to 192kHz with low power consumption
• Includes advanced DSP features: DRC, loudness compensation, and biquad filters
• Operates on a single 3V to 3.6V power supply

Audio Special Purpose Applications

• Digital audio interfacing in home theater systems
• Multi-channel speaker management in professional audio equipment
• High-fidelity audio processors requiring precise channel control

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'G4' against the manufacturer's current datasheet to confirm environmental compliance status and pinout compatibility. Ensure the 64-TQFP package dimensions match the target PCB footprint. Confirm that the 3V-3.6V supply range aligns with the system design requirements before procurement.

Audio Special Purpose Selection Notes

Select this component when an 8-channel digital audio solution with integrated DSP capabilities is required. It is suitable for designs needing support for high-resolution audio up to 192kHz. Ensure the application environment stays within the 0°C to 70°C operating temperature range. Verify that the host system can provide the necessary I2C and I2S signals for configuration and data input.

Audio Special Purpose Part Context

This part belongs to the TAS5508 series of digital audio PWM processors. It is functionally similar to the TAS5508B but may differ in packaging or compliance markings indicated by the suffix. It serves as a central processing unit for multi-channel audio systems, replacing discrete DSP and amplifier driver combinations.

Audio Special Purpose Replacement Considerations

Check the official TI datasheet for direct pin-to-pin replacements within the TAS5508 family. Verify if the TAS5508CPAG or other variants offer identical electrical characteristics and software compatibility for the specific application.
