Electrostatic Discharge Warning

2.1 Electrostatic Discharge Warning
Many of the components on the TAS3308EVM 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.
Failure to observe ESD handling procedures may result in damage to EVM
components.
2.2

Unpacking the EVM

Upon opening the TAS3308EVM package, please check to make sure that the following items are
included:
• TAS3308EVM board using one TAS3308DCP (1 pc.)
• PurePath CD-ROM containing data sheets, application reports, user guides, Gerber files, and PC
software tools (1 pc.)
If any of these items are missing, please contact the Texas Instruments Product Information Center
nearest you to inquire about a replacement.

Power Supply Setup

The TAS3308EVM is powered via the ±9 V terminals or the 9 V (center hot) power connectors, PJ1 and
PJ2. The TAS3308 EVM generates a 5-V, –5-V, and 3.3-V internal supplies that are fed to the
TAS3308EVM components.
Set the power supplies to ±9 V. Then turn off the supplies and them to the EVM.
Once the cables are connected, switch on the power supply. Current consumption should be less than
shown in Table 2-1, if higher switch off and double check the cabling.

The digital audio inputs can be connected to the board in two ways, either in the SPDIF format optical
TOSLINK input, OPTO1, or in I
shown in Chapter 3.
