TAS5508BPAGR

Audio Special Purpose Overview

The Texas Instruments TAS5508BPAGR is an eight-channel digital audio PWM processor designed for multichannel speaker systems. It integrates a Digital Audio Processor (DAP) with input crossbar mixing, biquad filters, bass/treble controls, loudness compensation, and dynamic range control (DRC). The device accepts serial audio data via I2S or left/right-justified interfaces at sampling rates from 32 kHz to 192 kHz. It operates on a single 3 V to 3.6 V supply within a 64-TQFP package (10x10 mm). Key features include programmable volume, automute, power-supply volume control (PSVC), and AM interference avoidance.

Audio Special Purpose Feature Summary

• Eight-channel digital audio processing with integrated DAP architecture
• Supports I2C serial control interface for register configuration
• Includes dynamic range control (DRC), loudness compensation, and biquad filters
• Operates with 3 V to 3.6 V supply voltage in a 64-TQFP package

Audio Special Purpose Applications

• Digital audio interfacing in multichannel speaker systems
• DVD receivers and home theater audio processors
• Automotive audio systems requiring channel management

Audio Special Purpose Procurement Notes

Verify the 'R' suffix indicates Tape & Reel packaging as per local source data. Confirm the specific revision level against the datasheet SLES162B. Ensure compatibility with 3V–3.6V logic levels for I2C and serial audio interfaces. Check for moisture sensitivity handling requirements during storage and assembly.

Audio Special Purpose Selection Notes

Select this component when eight independent channels of digital audio processing are required. It is suitable for designs needing integrated DSP functions like crossover, EQ, and DRC without external processors. Verify that the system supports I2S or standard serial audio formats. Ensure the PCB layout accommodates the 64-TQFP footprint and thermal dissipation needs.

Audio Special Purpose Part Context

The TAS5508B series is part of Texas Instruments' digital audio PWM processor family. It serves as a pre-driver for Class-D amplifiers, handling all digital signal processing before modulation. The BPAGR variant specifically denotes the tape-and-reel packaging option for automated surface-mount assembly.

Audio Special Purpose Replacement Considerations

Check for direct pin-compatible upgrades within the TAS5508 family. Verify if TAS5508CPAG offers necessary feature parity. Review TI documentation for any obsolescence notices or recommended design alternatives for legacy projects.
