Part Number: TAS5704

Function: 20-W Stereo Digital Audio Power Amplifier With Feedback

Package: HTQFP 64 Pin Type

Manufacturer: Texas Instruments

Pinouts:

 

Description

The TAS5704 is a 20-W, efficient, digital audio power amplifier for driving stereo bridge-tied speakers. Two serial data inputs allow processing of up to four discrete audio channels and seamless integration to most digital audio processors accepting a wide range of input data and clock rates. A hardware configurable data path allows these channels to be routed to the internal speaker drivers or output via the subwoofer PWM outputs.

Features

1.  Audio Input/Output

(1) 20-W into an 8-Ω Load From an 18-V Supply

(2) Two Serial Audio Inputs (Four Audio Channels)

(3) Supports Multiple Output Configurations:
– 2-Ch Bridged Outputs (20 W × 2)
– 4-Ch Single-Ended Outputs (10 W × 4)
– 2-Ch Single-Ended + 1-Ch Bridged (2.1) (10 W × 2 + 20 W)

2. Closed Loop Power Stage Architecture

(1) Improved PSRR Reduces Power Supply Performance Requirements

(2) Higher Damping Factor Provides for Tighter, More Accurate Sound With Improved Bass Response

(3) Lower EMC Emissions

(4) Output Power is Independent of Supply Voltage Variation
