The TAS5142DDV6EVM2 PurePath Digital™ customer evaluation module demonstrates the integrated circuits TAS5142DDV and TAS5086DBT from Texas Instruments (TI).
The TAS5142DDV is a high-performance, integrated stereo digital amplifier power stage designed to drive 4 Ω speakers at up to 100 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.
TAS5086DBT is a high-performance 32-bit (24-bit input) multichannel PurePath Digital pulse width modulator (PWM) based on Equibit technology with a new, fully symmetrical AD modulation scheme.
This EVM is configured with 6 BTL channels.
This EVM, together with a TI input-USB board, is a complete 5.1 channel digital audio amplifier system that includes digital input (S/PDIF), analog inputs, interface to PC, and DAP features like digital volume control, input and output multiplexers.
