The TAS5162DDV6EVM PurePath Digital™ customer evaluation module 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. 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). There are configuration option for power stage failure protection and a mini-jack connector for headphone.
This 5.1 system is designed for home theater applications such as A/V receivers, DVD receivers, DVD mini-component systems, or home theater in a box (HTIB).
