... It also utilizes cir- cuitry to reduce “clicks and pops” during device turn-on. Note 1: An LM4863MTE which has been properly mounted to the circuit board will deliver 2.2W into 4 . The other package options for the LM4863 will deliver 1.1W into 8 . See the Application Information section for LM4863MTE usage information ...

... With low impedance loads, the output power at the loads is heavily dependent on trace resistance from the output pins of the LM4863. Traces from the output of the LM4863MTE to the load or load connectors should be as wide as practical. Any resistance in the output traces will reduce the power de- livered to the load ...
