Overview
Overview
The TAS5352DDV6EVM PurePath Digital™ customer evaluation module demonstrates the integrated
circuits TAS5352DDV and TAS5518PAG from Texas Instruments (TI).
circuits TAS5352DDV and TAS5518PAG from Texas Instruments (TI).
The TAS5352DDV is a high-performance, integrated stereo Digital Amplifier Power Stage designed to
drive four speakers at up to 125 W per channel. The device incorporates TI’s Equibit™ technology and is
designed to be used with TI’s Equibit™ 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) multichannel 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 four BTL channels, one PBTL (parallel BTL) channel for the center channel,
and a subwoofer lineout using the DRV600 line driver.
and a subwoofer lineout using the DRV600 line driver.
The DRV600RTJ is a stereo line driver designed to allow the removal of the DC-blocking capacitors for
reduced component count and cost. The DRV600RTJ is ideal for single-supply electronics where size and
cost are critical design parameters. The DRV600RTJ is capable of driving2 Vrms into a 600-

load with a
3.3-V supply. The DRV600RTJ has a fixed gain of –1.5 V/V. Independent shutdown control for the left
and right audio channels is implemented.

This EVM, together with a TI Input-USB board 2, is a complete 5-channel plus subwoofer line output
digital audio amplifier system which includes digital input (S/PDIF), analog inputs, interface to a personal
computer (PC), and DAP features like digital volume control, input and output mixers, automute, tone
controls, loudness, EQ filters, and dynamic range compression (DRC). Configuration options are available
for power stage failure protection.
