TAS5028PAGRG4

Audio Special Purpose Overview

The TAS5028PAGRG4 is an 8-channel digital audio PWM processor from Texas Instruments, part of 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 32kHz to 192kHz and interfaces via I2C and I2S. Key electrical parameters include an operating temperature range of 0°C to 70°C. It functions as a modulator for digital audio interfacing applications.

Audio Special Purpose Feature Summary

• 8-Channel Digital Audio Processing with integrated DAP architecture
• Supports I2S, Left Justified, and Right Justified serial data formats
• Built-in bass/treble controls, volume management, and auto mute
• I2C serial control interface for configuration and status monitoring

Audio Special Purpose Applications

• Digital Audio Interfacing
• DVD Receivers
• Multi-channel speaker systems

Audio Special Purpose Procurement Notes

Verify the 64-TQFP package dimensions and tape & reel packaging specifications against the latest datasheet before procurement. Confirm that the 3V to 3.6V supply voltage requirements align with the target system design. Ensure compatibility with I2C slave address 0x36 and required serial clock frequencies.

Audio Special Purpose Selection Notes

Select this component for designs requiring up to 8 independent audio channels with digital processing capabilities. Ensure the host controller supports the necessary I2C and I2S protocols. Verify that the 0°C to 70°C operating temperature range meets the environmental constraints of the final application.

Audio Special Purpose Part Context

This part belongs to the TAS5028 family of digital audio PWM processors. The PAGRG4 suffix indicates the specific 64-TQFP package variant and RoHS compliance status. It is designed to work in conjunction with Texas Instruments power stages for complete audio solutions.

Audio Special Purpose Replacement Considerations

Check for direct pin-to-pin replacements within the TAS5028 family or newer generations like the TAS5518. Verify functional equivalence regarding channel count, interface support, and processing features before substitution.
