Hi All,
I have built the TAS3308 LC EVM into a powered speaker and providing 5V to the EVM to power the board when the usb is not connected.
When the back is on the speaker it seems that after so long when everything gets to temprature that the EVM keeps momentaryly going into reset only for a brief second.
If i leave the back off the speaker then the EVM does not go into reset at all!!!!!!
Nothing on the EVM feels particularly warm or like it is over heating.
Any ideas why it is doing this and what is sensing the heat?
Also with the back on the speaker and powering with USB aswell as the 5V i am supplying, the EVM does not go into reset!!!!
All a littlte bit confusing.....
Should i try feeding in 3.3v instead of 5 and bypassing the VR1 when no USB is connected?
Thanks for your time :)
Jamie
