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.
The TAS5086 is a six-channel digital pulse-width modulator (PWM) that provides advanced performance
and a high level of system integration. The TAS5086 is designed to interface seamlessly with most audio
digital signal processors and MPEG decoders, accepting a wide range of input data and clock formats.
This EVM is configured with four single-ended (SE) channels and two bridge-tied load (BTL) channels for
center and subwoofer channel.
Together with a TI input-USB board, this EVM is a complete 5.1-channel digital audio amplifier system
which includes digital input (S/PDIF), analog inputs, interface to PC, and DAP features like digital volume
control, input and output multiplexers, and automute. A configuration option is available for power-stage
failure protection.
