TAS5508BPAGRG4

Audio Special Purpose Overview

The TAS5508BPAGRG4 is an 8-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 voltage and supports sampling rates from 32kHz to 192kHz. Packaged in a 64-TQFP (10x10 mm) case, it functions as a modulator for digital audio interfacing applications within the specified operating temperature range of 0°C to 70°C.

Audio Special Purpose Feature Summary

• Integrates an 8-channel Digital Audio Processor (DAP) with input crossbar mixer, biquad filters, and dynamic range control.
• Supports I2C serial-control interface and I2S, Left-Justified, or Right-Justified serial audio data formats.
• Includes advanced processing features such as loudness compensation, bass/treble controls, and AM interference avoidance.
• Provides programmable volume, automute, and mute controls with configurable slew rates.

Audio Special Purpose Applications

• Digital audio interfacing systems
• DVD receivers
• Multichannel audio power amplifier systems

Audio Special Purpose Procurement Notes

Verify the package type matches the required 64-TQFP form factor. Confirm that the operating environment stays within the 0°C to 70°C temperature range. Ensure the system power supply is regulated between 3V and 3.6V. Check for compatibility with the I2C slave addresses 0x36 and 0x37 during design integration.

Audio Special Purpose Selection Notes

Select this component when an integrated solution for 8-channel digital audio processing and PWM modulation is required. It is suitable for designs needing flexible channel configuration via I2C registers. Consider the 64-TQFP footprint for PCB layout constraints. Verify that the target application supports the specified 32kHz to 192kHz sampling rate range.

Audio Special Purpose Part Context

This part belongs to the TAS5508B series of 8-channel digital audio PWM processors. It serves as a bridge between digital audio sources and Class-D power amplifiers, handling signal processing tasks internally to reduce external component count.
