8 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.

8.1 Application Information

This section describes a 2.1 Master and Slave application. The Master is configured as stereo outputs and the
Slave is configured as mono PBTL output.

8.2 Typical Application

A 2.1 solution, U1 TPA3116D2 in Master mode 400 kHz, BTL, gain if 20 dB, power limit not implemented. U2 in
Slave, PBTL mode gain of 20 dB. Inputs are connected for differential inputs.
