2 Quick Setup Guide

This chapter describes the TAS5630DKD2EVM board in regards to power supply and system interfaces.

The chapter 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 TAS5630DKD2EVM for device evaluation

2.1

Electrostatic Discharge Warning

Many of the components on the TAS5630DKD2EVM 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 TAS5630DKD2EVM package, ensure that the following items are included:

• 1 pc. TAS5630DKD2EVM board using one TAS5630DKD.

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.

3 Protection

Protection

This section describes the short-circuit protection and fault-reporting circuitry of the TAS5630 device.

3.1

Short-Circuit Protection and Fault-Reporting Circuitry

The TAS5630 is a self-protecting device that provides fault reporting (including high-temperature protection and short-circuit protection). The TAS5630 is configured in back-end auto-recovery mode, and therefore; resets automatically after all errors (M1, M2, and M3 is set low); see the data sheet ( SLES220 ) for further explanation. This mean that the device restart itself after an error occasion and report through the SD error signal.

3.2

Fault Reporting

The OTW and SD outputs from TAS5630 indicate fault conditions. See the TAS5630 data manual for a description of these pins.

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 power supply 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 90°C. The EVM is designed to operate properly with certain components above 125°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.
