Quick Setup Guide
This section describes the TAS5615DKD2EVM board in regards to power supply and system interfaces.
The section provides information regarding handling and unpacking, absolute operating conditions, and a
description of the factory default switch and jumper configuration.
This section provides a step–by–step guide to configuring the TAS5615DKD2EVM for device evaluation
2.1
Electrostatic Discharge Warning
Many of the components on the TAS5615DKD2EVM are susceptible to damage by electrostatic discharge
(ESD). Customers are advised to observe proper ESD handling precautions when unpacking and handling
the EVM, including the use of a grounded wrist strap at an approved ESD workstation.
CAUTION
Failure to observe ESD handling procedures may result in damage to EVM
components.
2.2
Unpacking the EVM
On opening the TAS5615DKD2EVM package, ensure that the following items are included:
• 1 pc. TAS5615DKD2EVM board using one TAS5615DKD.

If any of the items are missing, contact the Texas Instruments Product Information Center nearest you to
inquire about a replacement.
2.3
Power Supply Setup
To power up the EVM, one power supply is needed. An onboard, switched voltage regulator supplies
system power, logic, and gate-drive. The power supply is connected to the EVM using connector J15.
NOTE: When powering up, set switch SW11 to the RESET position.

CAUTION
Applying voltages above the limitations given in may cause permanent damage
to your hardware
NOTE: The length of power supply cable must be minimized. Increasing length of PSU cable is
equal to increasing the distortion for the amplifier at high output levels and low frequencies.
2.4
Applying Input Signal
It is possible to apply either a single-ended input signal to J20 and J21 or a differential input signal to J24
and J25.
NOTE: If a single-ended input signal is applied, insert jumpers in the header J24 and J25.
If a single ended input signal is applied please insert jumpers in
the header J24 and J25

Protection
This section describes the short-circuit protection and fault-reporting circuitry of the TAS5615 device.
3.1
Short-Circuit Protection and Fault-Reporting Circuitry
The TAS5615 is a self-protecting device that provides fault reporting (including high-temperature
protection and short-circuit protection). The TAS5615 is configured in back-end, auto-recovery mode, and
therefore; resets automatically after all errors (M1, M2, and M3 are set low); see the data sheet
(SLES220) for further explanation. This means that the device restarts itself after an error occasion and
reports through the SD error signal.
3.2
Fault Reporting
The OTW and SD outputs from TAS5615 indicate fault conditions. See the TAS5615 data sheet for a
description of these pins.

EVALUATION BOARD/KIT IMPORTANT NOTICE
Texas Instruments (TI) provides the enclosed product(s) under the following conditions:
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES
ONLY and is not considered by TI to be a finished end-product fit for general consumer use. Persons handling the product(s) must have
electronics training and observe good engineering practice standards. As such, the goods being provided are not intended to be complete
in terms of required design-, marketing-, and/or manufacturing-related protective considerations, including product safety and environmental
measures typically found in end products that incorporate such semiconductor components or circuit boards. This evaluation board/kit does
not fall within the scope of the European Union directives regarding electromagnetic compatibility, restricted substances (RoHS), recycling
(WEEE), FCC, CE or UL, and therefore may not meet the technical requirements of these directives or other related directives.
Should this evaluation board/kit not meet the specifications indicated in the User’s Guide, the board/kit may be returned within 30 days from
the date of delivery for a full refund. THE FOREGOING WARRANTY IS THE EXCLUSIVE WARRANTY MADE BY SELLER TO BUYER
AND IS IN LIEU OF ALL OTHER WARRANTIES, EXPRESSED, IMPLIED, OR STATUTORY, INCLUDING ANY WARRANTY OF
MERCHANTABILITY OR FITNESS FOR ANY PARTICULAR PURPOSE.
The user assumes all responsibility and liability for proper and safe handling of the goods. Further, the user indemnifies TI from all claims
arising from the handling or use of the goods. Due to the open construction of the product, it is the user’s responsibility to take any and all
appropriate precautions with regard to electrostatic discharge.
EXCEPT TO THE EXTENT OF THE INDEMNITY SET FORTH ABOVE, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY
INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES.
TI currently deals with a variety of customers for products, and therefore our arrangement with the user is not exclusive.
TI assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or
services described herein.
Please read the User’s Guide and, specifically, the Warnings and Restrictions notice in the User’s Guide prior to handling the product. This
notice contains important safety information about temperatures and voltages. For additional information on TI’s environmental and/or
safety programs, please contact the TI application engineer or visit www.ti.com/esh.
No license is granted under any patent right or other intellectual property right of TI covering or relating to any machine, process, or
combination in which such TI products or services might be or are used.
FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES
ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio
frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are
designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may
cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may
be required to correct this interference.
EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the input voltage range of 0 V to 50 V for the output stage and 15 V to 20 V for the system supply
and the output voltage range of 0 V to 50 V.
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions
concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM.
Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 75°C. The EVM is designed to operate
properly with certain components above 75°C as long as the input and output ranges are maintained. These components include but are
not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified
using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation,
please be aware that these devices may be very warm to the touch.
