TAS5132DDV2EVM - User Guide

The TAS5132DDV2EVM is composed of two separate modules, the HPL-MC012 Modulator/Controller
Module and the TAS5132DDV2EVM Amplifier Module. They are designed so that the user can separate
the two modules and connect the TAS5132DDV2EVM Amplifier Module in to a target system via a ribbon
cable. Keep this ribbon cable as short as possible to avoid degradation in the PWM signals.
The TAS5132DDV2EVM PurePath Digital ™ customer evaluation amplifier module demonstrates two
audio integrated circuits — the TAS5086 and the TAS5132 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 TAS5132DDV is a compact, high-power, digital amplifier power stage designed to drive an 8- Ω
loudspeaker up to 20 W/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.
