Overview
The TAS5066−5111D6EVM PurePath Digitalt 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 Equibit
TM
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 TAS5066−5111D6EVM, 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.
