TAS5028PAGR

Audio Special Purpose Overview

The Texas Instruments TAS5028PAGR is an 8-channel digital audio PWM processor belonging to the PurePath Digital series. It operates on a 3V to 3.6V supply within a 64-TQFP package (10x10 mm). The device supports sampling rates from 32 kHz to 192 kHz and features I2C and I2S interfaces for control and data. Key specifications include a 32-bit resolution, surface mount mounting type, and an operating temperature range of 0°C to 70°C. It integrates digital audio processing capabilities including volume control, mute functions, and bass/treble adjustments.

Audio Special Purpose Feature Summary

• 8-Channel Digital Audio Processing with 32-bit resolution
• Integrated Digital Audio Processor (DAP) with input/output mixers
• Supports I2S, Left Justified, and Right Justified serial data formats
• Built-in Bass/Treble controls, Volume, Auto Mute, and AM interference avoidance

Audio Special Purpose Applications

• Digital Audio Interfacing
• DVD Receivers
• Home Theater Systems

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'GR' indicates Tape & Reel packaging as per local product fields. Confirm the 64-TQFP physical dimensions match design constraints. Ensure the I2C slave address 0x36 compatibility with the host controller. Check RoHS compliance status before integration.

Audio Special Purpose Selection Notes

Select this component for designs requiring multi-channel digital audio processing without external DSPs. Ensure the power supply voltage remains between 3V and 3.6V. Verify that the host system supports the required I2S or I2C interface protocols. Consider the 64-pin TQFP footprint for PCB layout planning.

Audio Special Purpose Part Context

The TAS5028 is part of Texas Instruments' PurePath Digital family, designed for high-performance digital audio applications. It serves as a central processing unit for digital speaker systems, handling audio data conversion and modulation. The PAGR variant specifically denotes the tape and reel packaging option for automated assembly.

Audio Special Purpose Replacement Considerations

Check for direct pin-compatible alternatives within the TAS5028 series or newer generations like the TAS55xx if additional features such as ASRC are needed. Verify electrical parameters and register compatibility when substituting.
