Figure 3. EVM Connections Diagram

The connections diagram shows a stereo output drive system using the TPA1517DWP
EVM (SLOP106) configured to drive stereo speakers.  A standard 1/8” stereo input
jack is shown providing a convenient connection to CD players or other commercial
sources of audio signals.

Key Features:
1) Stereo Single Ended (SE) drive of 4 ohm or 8 ohm speakers.  The input and output
coupling capacitors are included on the EVM which makes EVM hookup very simple.

2) Mute of the Speaker Drive - Either pressing the Mute switch or providing an
external TTL control of the Mute input allows one to mute the speaker output.

3) The PowerPAD package is thermally connected the PCB ground plane for
enhanced thermal performance
