Overview
The TAS5162DDV6EVM PurePath Digital ™ customer evaluation module (Figure 1 ) demonstrates the
integrated circuits TAS5162DDV and TAS5086DBT from Texas Instruments (TI).

The TAS5162DDV is a high-performance, integrated stereo digital amplifier power stage designed to drive
6- Ω speakers at up to 210 W per channel. The device incorporates PurePath Digital™ technology and is
designed to be used with PurePath Digital™ modulators (Figure 2 ). This system requires only a simple,
passive demodulation filter to deliver high-quality, high-efficiency audio amplification.
TAS5086DBT is a high-performance, 32-bit (24-bit input), multichannel PurePath Digital™ pulse width
modulator (PWM) based on Equibit™ technology with fully symmetrical analog-to-digital modulation
scheme.
This EVM is configured with four single-ended (SE) channels and two bridge-tied load (BTL) channels.
This EVM, together with a TI input-USB board, is a complete 5.1 channels, 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). Table 1 lists the key parameters of the EVM. There are configuration option for
power stage failure protection and a mini-jack connector for headphone.
