The TAS5162DKD6EVM PurePath Digital ™ customer evaluation module demonstrates the integrated
circuits TAS5162DKD and TAS5518PAG from Texas Instruments.

The TAS5162DKD is a high-performance, integrated stereo Digital Amplifier Power Stage designed to
drive 6-

speakers at up to 210 W per channel. The device incorporates PurePath Digital™ technology

and is designed to be used with PurePath Digital™ modulators. This system requires only a simple
passive demodulation filter to deliver high-quality, high-efficiency audio amplification.

TAS5518PAG is a high performance 32 bit (24 bit input) multi channel PurePath Digital™ Pulse Width
Modulator (PWM) based on Equibit™ technology with fully symmetrical AD modulation scheme. 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).

This EVM is configured with 4 BTL channels and 1 PBTL (parallel BTL) channel for the subwoofer
channel.

This EVM, together with a TI input-USB board, is a complete 5 channels + subwoofer line output 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 mixers, automute, tone controls, loudness, EQ filters
and dynamic range compression (DRC). There are configuration options for power stage failure protection,
and a phono connector for subwoofer line output.
