Introduction

The TAS5612L-TAS5614LDDVEVM PurePath™ EVM demonstrates the current version of TAS5612LDDV

or TAS5614LDDV integrated circuit power stage with TAS5538DGG from Texas Instruments (TI).

The TAS5612L and TAS5614L are high-performance, integrated Stereo Feedback Digital Amplifier Power

Stages designed to drive 4Ω speakers at up to 150W per channel for TAS5614LDDV and 125W per

channel for TAS5612LDDV. They require only a passive demodulation filter to deliver efficient high quality

audio amplification.

TAS5538DGG is a high performance 32 bit (24 bit input) multi channel PurePath™ Digital Pulse Width

Modulator (PWM) with fully symmetrical AD modulation scheme. The device also has Digital Audio

Processing (DAP) that provides 48 bit signal processing, advanced performance and a high level of

system integration.

This EVM can be configured as 2 BTL channels for stereo evaluation or 1 PBTL (parallel BTL) channel for

subwoofer evaluation. Together with a TI Input-USB Board 3, it provides a complete stereo 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 options for power stage failure protection.

NOTE: TAS5612L-TAS5614LDDVEVM IS SHIPPED WITH THE CURRENT VERSION OF

TAS5614L INSTALLED. TO EVALUATE THE CURRENT VERSION OF TAS5612L

PLEASE VISIT THE PRODUCT FOLDER AT www.ti.com AND REQUEST A FREE

SAMPLE; AND, REPLACE THE TAS5614L WITH TAS5612L.

NOTE: The heatsink in TAS5612L-TAS5614LDDVEVM is designed to comply with time

requirements of the “Amplifier Rule”, US Federal Trade Commission 16 CFR 432, when the

EVM is operated at power levels specified above. If continuous operation at specified output

power is required it is necessary to provide forced air flow through the heatsink.

(The FTC regulation specifies operation in 25°C ambient temperature for one hour at 1/8

specified output power (18.75W per channel for TAS5614LDDVEVM, 15.63W per channel

for TAS5612LDDVEVM) and then for 5 minutes at specified output power (150W per channel

for TAS5614LDDVEVM, 125W per channel for TAS5612LDDVEVM). Then distortion vs.

output power can be measured. TAS5612L-TAS5614LDDVEVM provides specified output

power for several minutes or more without thermal shutdown. THD is not specified for this

test but is typically near 10%.)
