10 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

10.1 Application Information

These typical connection diagrams highlight the required external components and system level connections for

proper operation of the device. Each of these configurations can be realized using the Evaluation Modules

(EVMs) for the device. These flexible modules allow full evaluation of the device in the most common modes of

operation. Any design variation can be supported by TI through schematic and layout reviews. Visit e2e.ti.com for

design assistance and join the audio amplifier discussion forum for additional information.
