10 HANDLING
Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is
desirable to take normal precautions appropriate to handling integrated circuits.
11 THERMAL CHARACTERISTICS
The thermal resistance depends on the flex used. The TDA5155X is shipped in naked dies form.
