Page 14: Electrostatic Discharge Warning
Electrostatic Discharge Warning Electrostatic Discharge Warning Many of the components on the TAS3108EVM2 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. -
Page 15: Power Supply Setup
Power Supply Setup Power Supply Setup The TAS3108EVM2 is powered via the DAC8-DIT2 board or another output board, like a TAS5086-5186EVM. The DAC8-DIT2 board generates a +5-V supply that is fed to the TAS3108EVM2. The +5-V supply is further regulated to +3.3 V with the aid of a low-dropout linear regulator, U31. -
