Product InformationDescription View TAS5086-5142V6EVMThe TAS5086-5142V6EVM PurePath Digital™ customer evaluation amplifier module demonstrates two audio integrated circuits, TAS5086 and TAS5142, from Texas Instruments (TI). The TAS5086DBT is a high-performance, 32-bit (24-bit input) multichannel PurePath Digital™ pulse width modulator (PWM) based on Equibit™ technology, with a fully symmetrical AD modulation scheme. It accepts an input sample rate from 32 kHz to 192 kHz. The TAS5142DDV is a compact, high-power, digital amplifier power stage designed to drive a 4-Ω loudspeaker up to 100 W/10% THD+N. It contains integrated gate drivers, four matched and electrically isolated enhancement-mode N-channel power DMOS transistors, and protection/fault-reporting circuitry. In this application output power is limited to 50 W due to thermal constraints. The DDV package has a PowerPAD™ on the top side for heat transfer through a heat sink. The heat sink in this design is for evaluation purpose only. This EVM, together with a TI input-USB board, is a complete 5.1-channel digital audio amplifier system, which includes digital input (S/PDIF), analog inputs, interface to PC, and features, such as digital volume control, input and output multiplexers, auto mute, and simple bass management. There are configuration options for power-stage failure protection and a mini-jack connector for headphones. This system is designed for home theater applications, such as flatscreen TVs, DVD minicomponent systems, home theater in a box (HTIB), or DVD receivers. Features
