Introduction
The TAS5612L-TAS5614LDDVEVM PurePath™ EVM demonstrates the current version of TAS5612LDDV
or TAS5614LDDV integrated circuit power stage with TAS5558 from Texas Instruments (TI).
The TAS5612L and TAS5614L are high-performance, integrated Stereo Feedback Digital Amplifier Power
Stages designed to drive 4-Ω speakers at up to 150 W per channel for TAS5614LDDV and 125 W per
channel for TAS5612LDDV. They require only a passive demodulation filter to deliver efficient high quality
audio amplification.
The TAS5558 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 the TAS5614L

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%.)

1.) These preliminary evaluation schematics are intended for use for PRELIMINARY ENGINEERING DEVELOPMENT AND EVALUATION PURPOSES ONLY and are not considered by
Texas Instruments to be fit as a basis for establishing production products or systems. This information may be incomplete in several respects, including but not limited to information
relating to required design, marketing, and/or manufacturing-related protective considerations and product safety measures typically found in the end-product incorporating the goods.
2.) Accordingly, neither TI nor its suppliers warrant the accuracy or completeness of the information, text, graphics, links orother items contained within the Materials. TI may make
changes to the Materials, or to the products described therein, at any time without notice. TI makes no commitment to update the Materials.
3.) TI assumes no liability for applications assistance, customer product design, software performance, or services that may be described or referenced in the Materials. The user
assumes all responsibility and liability for proper and safe design and handling of goods. Accordingly, the user indemnifies TI from all claims arising from its use of the Materials.
4.) TI currently deals with various customers for products, and therefore our arrangement with the user will not be exclusive. TI makes no representations regarding the
commercial availability of non-TI components that may be referenced in the Materials.
5.) No license is granted under any patent right or other intellectual property right of TI covering or relating to any combination, machine, or process in which such TI products or
services might be or are used. Except as expressly provided herein, TI and its suppliers do not grant any express or implied right to you under any patents, copyrights,
trademarks, or trade secret information.
6.) Performance tests and ratings, to the extent referenced in the Materials, are measured using specific computer systems and/or components and reflect the approximate
performance of TI products as measured by those tests. Any difference in system hardware or software design or configuration may affect actual performance. Buyers should
consult other sources of information to evaluate the performance of systems or components they are considering purchasing.
7.) Resale of TI's products or services with statements different from or beyond the parameters stated by TI for that product or service in official TI data books or data sheets
voids all express and any implied warranties for the associated TI product or service, and is an unfair and deceptive businesspractice, and TI is not responsible for any such use.
8.) The Materials are copyrighted and any unauthorized use may violate copyright, trademark, and other laws. You may only download one copy for your internal use only,
unless you are specifically licensed to do otherwise by TI in writing. This is a license, not a transfer of title, and is subject to the following restrictions: You may not:
(a) modify the Materials (including any associated warranties, conditions, limitations or
notices) or use them for any commercial purpose, or any public display, performance, sale or
rental;

extent permitted by applicable law;
(c) remove any copyright or other proprietary notices from the Materials;
(d) transfer the Materials to another person. You agree to prevent any unauthorized copying
of the Materials. TI may terminate this license at any time if you are in breach of the terms
of this Agreement. Upon termination, you will immediately
destroy the Materials.

TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
