Texas Instruments  TAS5504-5142V4EVM

The TAS5504-5142V4EVM PurePath Digital™ customer evaluation amplifier moduledemonstrates two audio integrated circuits, TAS5504A and TAS5142, from TexasInstruments (TI).

The TAS5504APAG 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 TAS5142DDV is a compact, high-power, digital amplifier power stage designed todrive a 4-Ω loudspeaker up to 100 W/10% THD+N. It contains integrated gate drivers,eight matched and electrically isolated enhancement-mode N-channel power DMOStransistors, and protection/fault-reporting circuitry.

The DDV package has a PowerPAD™ on the top side for heat transfer through aheat sink. The heat sink in this design is for evaluation purpose only.

This EVM, together with a TI input-USB board, is a complete 4-channel (or2.1-channel) digital audio amplifier system that includes digital input (S/PDIF), analoginputs, interface to PC, and DAP features, such as digital volume control, input andoutput mixers, auto mute, equalization, tone controls, loudness, and dynamic rangecompression.

This system is designed for home theater applications, such as flatscreen TVs, DVDminicomponent systems, home theater in a box (HTIB), or DVD receivers.
