9.1.1 Typical Application
This section describes a 2.1 Master and Slave application. The Master (U1 TPA3126D2) is configured as stereo BTL outputs with 400-kHz switching frequency and no power limit implemented, and the Slave (U2) is configured as a mono PBTL output. Both U1 and U2 are setup with a gain of 26-dB. Inputs are connected for differential inputs.
