Stereo

The TAS2555EVM supports stereo mode (dual mono mode) through J21 and J22 and an optional stereo
adapter board or stereo ribbon cable.

Connect two TAS2555EVMs together side by side as shown in

Figure 5. Stereo Mode Using Two TAS2555EVMs

The top board is the left channel board. The other board is the right channel board and must be
configured to use the control interface from the left channel board. The TAS2555 on the left channel board
uses device address 0x98 and the TAS2555 on the right channel board uses device address 0x9A.
Remove the jumpers from J12 (ADR0), J19 (SCL), and J20 (SDA) on the right channel board.
