Page 2: Overview
................Physical Specifications Overview The TAS5132DDV6EVM PurePath Digital ™customer evaluation module demonstrates the integrated circuits TAS5132DDV and TAS5086DBT from Texas Instruments (TI). The TAS5132 is an integrated stereo digital amplifier power stage with an advanced protection system. The TAS5132 is capable of driving a 6-Ω bridge-tied load at up to 25 W per channel with low integrated noise at the output, low THD+N, and low idle power dissipation. -
Page 3: Integrated Purepath Digital™ Amplifier System
The EVM is delivered with cables and an input-USB board for connection to an input source and for control by a personal computer. TAS5132DDV6EVM Features • 6-channel PurePath Digital™ evaluation module (double-sided, plated-through PCB layout). • Self-contained protection system (short circuit and thermal). -
