Chapter 1SLEU074 – June 2006
Overview
The TAS5518-5152K8EVM PurePath Digital™ customer evaluation amplifier moduledemonstrates two audio integrated circuits, TAS5518 and TAS5152, from TexasInstruments (TI).
The TAS5518PAG is a high-performance 32-bit (24-bit input) multichannel PurePathDigital pulse-width modulator (PWM) based on Equibit™ technology, with a fullysymmetrical AD modulation scheme. It accepts input sample rates from 32 kHz to192 kHz. The device also has digital audio processing (DAP) that provides 48-bit signalprocessing, advanced performance, and a high level of system integration. The devicehas interfaces for headphone output and power supply volume control (PSVC).
The TAS5152DKD is a compact, high-power, digital amplifier power stage designed todrive a 4- Ωloudspeaker up to 125 W (10% THD+N). It contains integrated gate drivers,four matched and electrically isolated enhancement-mode N-channel power DMOStransistors, and protection/fault-reporting circuitry.
The DKD PowerPAD™ package top side allows heat transfer through a heatsink. Theheatsink in this design is for evaluation purposes only.
This EVM, together with a TI input-USB board, is a complete 7-channel digital audioamplifier system that includes digital input (S/PDIF), analog inputs, interface to PC, andDAP features, such as digital volume control, input and output mixers, auto mute,equalization, tone controls, loudness, dynamic range compression, and PSVC output.There are configuration options for stereo line level output, stereo headphone output,and power-stage failure protection.
This 6.1 system is designed for home-theater applications, such as A/V receivers, DVDminicomponent systems, home theater in a box (HTIB), DVD receivers, or plasmadisplay panels (PDPs).
