Personal Computer (PC) Configuration Tool for TAS5086 (TAS5086 GUI version 4.0 or later). This software comes on the compact disk in the EVM package.

2Overview

The TAS5102EVM and TAS5103EVM packages are composed of two separate modules, the HPL-MC012 Modulator/Controller Module and the TAS5102EVM or TAS5103EVM Amplifier Module. They are designed so that the user can separate the two modules and connect the TAS5102EVM or TAS5103EVM Amplifier Module into a target system via a ribbon cable. Keep this ribbon cable as short as possible to avoid degradation in the PWM signals.

The TAS5102 and TAS5103 customer evaluation amplifier modules each demonstrate two audio integrated circuits — the TAS5086 and the TAS5102 or TAS5103 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 fully symmetrical AD modulation scheme. It accepts an input sample rate from 32 kHz to 192 kHz. The device also has digital audio processing (DAP) that provides bass management, advanced performance, and a high level of system integration.

The TAS5102 is a compact, high-power, digital amplifier power stage designed to drive an 8-Ωloudspeaker up to 20 W/channel at 10% THD+N. It contains integrated gate-drive, four matched and electrically isolated enhancement-mode N-channel power DMOS transistors, and protection/fault-reporting circuitry. The DAD package has a PowerPAD™ package on the top side for heat transfer through a heat

sink. The heat sink in this design is for evaluation purposes only.
