TAS5504-5142V4EVM-TAS5504-5142V4 Evaluation Module

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

The TAS5504APAG is a high-performance 32-bit (24-bit input) multichannel PurePath Digital™ pulse width modulator (PWM) based on Equibit™ technology, with a fully symmetrical AD modulation scheme. It accepts input sample rates from 32 kHz to 192 kHz. The device also has digital audio processing (DAP) that provides 48-bit signal processing, advanced performance, and a high level of system integration. The device has interfaces for headphone output and power supply volume control (PSVC).

The TAS5142DDV is a compact, high-power, digital amplifier power stage designed to drive 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 DMOS transistors, and protection/fault-reporting circuitry.

The DDV package has a PowerPAD™ on the top side for heat transfer through a heat 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 (or 2.1-channel) digital audio amplifier system that includes digital input (S/PDIF), analog inputs, interface to PC, and DAP features, such as digital volume control, input and output mixers, auto mute, equalization, tone controls, loudness, and dynamic range compression.

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