Product details

TAS5508CPAG - 8-Channel Digital Audio PWM Processor for Class-D Systems (64-TQFP)
The TAS5508CPAG from Texas Instruments is an 8-channel digital audio PWM processor that converts serial digital audio inputs into multi-channel PWM outputs to drive external Class-D amplifier power stages. It targets AV receivers, car audio, and multi-channel amplified speaker platforms.

Product Introduction

The TAS5508CPAG is built for high-integration digital audio amplifier designs. It accepts multiple serial audio input channels and produces eight PWM output channels that can be used to drive external H-bridge or half-bridge Class-D power stages.

In system architecture, TAS5508 is often paired with a dedicated audio signal processor (for tuning/mixing) and downstream power stages. Its design emphasizes multi-channel scalability and a simplified interface approach for mainstream AV platforms.

The device is offered in a 64-pin TQFP package and is widely seen in designs that require multi-channel amplification with consistent digital control and integration.

Key Benefits

8-Channel PWM Output for Class-D

Enables compact multi-channel amplifier architectures by generating multiple PWM channels from digital audio inputs.

Flexible Audio Input Support

Designed to interface with common serial audio formats (e.g., I2S/justified formats) and multi-rate systems.

System Integration Friendly

Simplifies the digital-to-power stage interface and reduces glue logic for AV receiver and car audio mainboards.

Proven TI Audio Ecosystem

Works within TI's audio processing ecosystem (DSP + PWM + Class-D stages) for consistent platform development.

Technical Features

Multi-Channel Serial Audio Inputs

Supports multi-channel serial audio input paths for AV receiver and multi-speaker configurations.

High-Resolution PWM Processing

Designed for PWM generation suitable for Class-D output stages, supporting multi-rate audio operation.

Control Interface for Configuration

Register-controlled device behavior enables system-level tuning, configuration, and management (confirm details in datasheet).

Technical Specifications

Parameter Value / Condition
Function 8-channel digital audio PWM processor / modulator
Audio Channels Eight PWM output channels (system-dependent configuration)
Sampling Rate Support Common audio sampling rates (e.g., 32k–192k family capability; confirm exact modes in datasheet)
