Overview

The TAS5066−5111D6EVM PurePath Digital t customer evaluation module demonstrates two integrated circuits TAS5066 and TAS5111DAD from Texas Instruments (TI).

The TAS5066 is a high-performance 24-bit six-channel digital pulse width modulator (PWM) based on EquibitTM technology. The TAS5066 has a wide variety of serial input (I@S) options including right justified, left justified, and DSP data formats. It accepts I@S data with sample rates up to 192 kHz.

TAS5111 is a high-performance digital amplifier power stage designed to drive a 4-Ohm loudspeaker up to 85 W. It contains integrated gate-drivers, four matched and electrically isolated enhancement-mode N-channel power DMOS transistors and protection / fault-reporting circuitry.

The TAS5066−511 1D6EVM, together with a TI input board, is a complete digi- tal audio amplifier system that includes digital input (S/PDIF), analog input, in- terface to PC, digital volume control, and failure protection. The system was design for home theater applications such as DVD minicomponent systems, home theater in a box (HTIB), DVD receiver, A/V receiver, or TV sets.
